-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.

-// isAboutToUnderflow is something of a hack used to figure out when it might be

-// move on with a discontinuity.  If we had perfect knowledge of when we were
-// going to underflow, it would not be a hack, but unfortunately we do not.
-// Right now, we just take the PTS of the last sample queued, and check to see
-// if its presentation time is within kAboutToUnderflowThreshold from now.  If
-// it is, then we say that we are about to underflow.  This decision is based on
-// two (possibly invalid) assumptions.
-//
-// 1) The transmitter is leading the clock by more than
-//    kAboutToUnderflowThreshold.
-// 2) The delta between the PTS of the last sample queued and the next sample
-//    is less than the transmitter's clock lead amount.
-//
-// Right now, the default transmitter lead time is 1 second, which is a pretty
-// large number and greater than the 50mSec that kAboutToUnderflowThreshold is
-// currently set to.  This should satisfy assumption #1 for now, but changes to
-// the transmitter clock lead time could effect this.
-//
-// For non-sparse streams with a homogeneous sample rate (the vast majority of
-// streams in the world), the delta between any two adjacent PTSs will always be
-// the homogeneous sample period.  It is very uncommon to see a sample period
-// greater than the 1 second clock lead we are currently using, and you
-// certainly will not see it in an MP3 file which should satisfy assumption #2.
-// Sparse audio streams (where no audio is transmitted for long periods of
-// silence) and extremely low framerate video stream (like an MPEG-2 slideshow
-// or the video stream for a pay TV audio channel) are examples of streams which

+libnbaio (for "Non-Blocking Audio I/O") was originally intended to
+be a purely non-blocking API.  It has evolved to now include
+a few blocking implementations of the interface.
+
+Note: as used here, "short transfer count" means the return value for
+read() or write() that indicates the actual number of successfully
+transferred frames is less than the requested number of frames.
+
+Pipe
+----
+supports 1 writer and N readers
+
+no mutexes, so safe to use between SCHED_NORMAL and SCHED_FIFO threads
+
+writes:
+  non-blocking
+  never return a short transfer count
+  overwrite data if not consumed quickly enough
+
+reads:
+  non-blocking
+  return a short transfer count if not enough data
+  will lose data if reader doesn't keep up
+
+MonoPipe

- FUNCTION DESCRIPTION
-
- This function steps through all of the tools that are applied on a
- scalefactor band basis.
-
- The use of M/S stereo is checked for.  For M/S decoding to take
- place, ms_mask_map must be TRUE for that particular SFB, AND the Huffman
- codebook used must be < NOISE_HCB.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    coef =       Array of input coefficients.
-                 [Int32 *, length 1024]
-
-    q_format   = Array of q-formats, one per scalefactor band, for the
-                 entire frame.  In the case of tns_inv_filter, only the
-                 first element is used, since the input to tns_inv_filter
-                 is all of the same q-format.
-                 [Int * const, length MAX_SFB]
-
-    pFrameInfo = Pointer to structure that holds information about each group.
-                 (long block flag, number of windows, scalefactor bands
-                  per group, etc.)
-                 [const FrameInfo * const]
-
-    pTNS_frame_info = pointer to structure containing the details on each
-                      TNS filter (order, filter coefficients,
-                      coefficient res., etc.)
-                      [TNS_frame_info * const]
-
-    inverse_flag   = TRUE  if inverse filter is to be applied.
-                     FALSE if forward filter is to be applied.
-                     [Bool]
-
-    scratch_Int_buffer = Pointer to scratch memory to store the
-                           filter's state memory.  Used by both
-                           tns_inv_filter.
-                           [Int *, length TNS_MAX_ORDER]
-
- Local Stores/Buffers/Pointers Needed:
-    None
-
- Global Stores/Buffers/Pointers Needed:
-    None
-
- Outputs:
-    None
-
- Pointers and Buffers Modified:
-    coef[]   = TNS altered data.
-    q_format = q-formats in TNS scalefactor bands may be modified.
-
- Local Stores Modified:
-    None
-
- Global Stores Modified:
-    None
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
-    This function applies either the TNS forward or TNS inverse filter, based
-    on inverse_flag being FALSE or TRUE, respectively.
-
-    For the TNS forward filter, the data fed into tns_ar_filter is normalized
-    all to the same q-format.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    The input, coef, should use all 32-bits, else the scaling by tns_ar_filter
-    may eliminate the data.

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function is only invoked when short windows are present. It calculates
- the number of groups in one frame, and the scalefactor bandwidth of each
- scalefactor band in each group.
- All windows within one group share the same scalefactors and are interleaved
- on a scalefactor band basis. Within each group, the actual length of one
- scalefactor band equals to the number of windows times the number of
- coefficients in a regular scalefactor band.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall replace the contents of pFrameInfo->frame_sfb_top
- with the cumulative bandwidth of each scalefactor band in each group

- FUNCTION DESCRIPTION
-
-   These functions are used to decode huffman codewords from the input
-   bitstream using combined binary search and look-up table approach.
-
-   First the codewords are grouped and the input symbol is determined
-   which group it belongs. Then within that group, a look-up table is
-   used to determine which codeword the symbol is.
-   The table is created by ordering the codeword in the table according to their
-   normalized shifted binary value, i.e., all the codewords are left
-   shifted to meet the maximum codelength. Example, max codelength is
-   10, the codeword with lenth 3 will left shift by 7.
-   The binary values of after the shift are sorted.
-   Then the sorted table is divided into several partition.
-   At the VLC decoding period, input is read in at max codelenght.
-   The partition is decided using if-else logic.
-   Inside each partition, a look-up table is used to map the input value
-   to a correct symbol. Table entries can appear to be repeated according
-   to the humming distance between adjacent codewords.

- FUNCTION DESCRIPTION
-
- This function performs the inverse quantization of the spectral coeficients
- read from huffman decoding. It takes each input array value to the four
- thirds power, then scales it according to the scaling factor input argument
- ,and stores the result in the output array in a variable Q format
- depending upon the maximum input value found.

- * Processing in this function is performed in these steps:
- *
- * 1) Find the overall Q format for the entire group of inputs. This consists
- *    of:
- *    a) Finding the maximum input
- *    b) estimate the maximum output
- *    c) Using the table, get max ^ (4/3), taking into account the table is
- *       in q format.
- * 2) For each array element, see if the value is directly inside the table.
- *    a) If yes, just multiply by table value by itself, then shift as
- *       appropriate.
- *    b) If no, get an approximation (described below) for x ^ (1/3) by linearly
- *       interpolating using lower values in the table, then multiply by a
- *       correction factor, then multiply by x (see below).
- *
- * It more accurate to interpolate x ^ (1/3) then x ^ (4/3), so that is stored
- * in the lookup table. For values not in the table, interpolation is used:
- *
- *  We want y = x ^ (4/3) = x * (x ^ (1/3))
- *
- *  Let     x = w * (2 ^ m)  where m is a constant, = ORDER
- *
- *  then     x ^ (1/3) = w ^ (1/3) * (2 ^ (m/3))
- *
- *  w is most likely not an integer, so an interpolation with floor(w) and
- *  ceil(w) can be performed to approximate w ^ (1/3) by getting values out of
- *  the table. Then to get x ^ (1/3), multiply by FACTOR. If m = 0, 3, 6,
- *  then FACTOR is a simple power of 2, so a shift can do the job.
- *
- *  The actual code employs some more tricks to speed things up, and because
- *  the table is stored in Q format.
- *
- *  Rather than saving the sign of each input, the unsigned value of
- *  abs(x) ^ (1/3) is multiplied by the signed input value.

- REVISION HISTORY
-
- Description:
-            (1) Eliminated search for max in the main loop.
-            (2) Reduced precision on w_256rx4 from Q15 to Q10
-
- Description:
-            (1) Created function fft_rx4_long_no_max to overcome LTP problem.
-
- Description:
-            (1) Modified shift so the accumulation growths faster than the
-                downshift, so now the input can be as high as 1.0 and saturation
-                will not occurre. The accumulation times the Q10 format will
-                never exceed 31 bits. This increases precision
-            (2) Eliminated unneeded data moves, used before for max search.
-            (3) Eliminated function fft_rx4_long_no_max.
-
- Description:
-            (1) Added comment to explain max search elimination and
-                Q format during multiplications

- FUNCTION DESCRIPTION
-
-    Fast Fourier Transform, radix 4 with Decimation in Frequency and block
-    floating point arithmetic.
-    The radix-4 FFT  simply divides the FFT into four smaller FFTs. Each of
-    the smaller FFTs is then further divided into smaller ones and so on.
-    It consists of log 4 N stages and each stage consists of N/4 dragonflies.
-
-    An FFT is nothing but a bundle of multiplications and summations which
-    may overflow during calculations.
-
-
-    This routine uses a scheme to test and scale the result output from
-    each FFT stage in order to fix the accumulation overflow.
-
-    The Input Data should be in Q13 format to get the highest precision.
-    At the end of each dragonfly calculation, a test for possible bit growth
-    is made, if bit growth is possible the Data is scale down back to Q13.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    This function should provide a fixed point FFT for an input array
-    of size 256.

- REVISION HISTORY
-
- Description:
-            (1) Eliminated search for max in the main loop.
-            (2) Simplified the function by eliminating different conditions
-                for exp.
-            (3) Reduced precision on w_64rx4 from Q15 to Q12, so now the
-                input can be as high as 1.0 and saturation will not occurre
-                because the accumulation times the new Q12 format will never
-                exceed 31 bits.
-
- Description:
-            (1) Added comment to explain max search elimination and
-                Q format during multiplications
-            (2) Increased down shift from 1 to 2, to ensure that 32-bit
-                numbers will not overflow when 2 consecutive adds are done
-                This was found during code review.

- FUNCTION DESCRIPTION
-
-    Fast Fourier Transform, radix 4 with Decimation in Frequency and block
-    floating point arithmetic.
-    The radix-4 FFT  simply divides the FFT into four smaller FFTs. Each of
-    the smaller FFTs is then further divided into smaller ones and so on.
-    It consists of log 4 N stages and each stage consists of N/4 dragonflies.
-
-    An FFT is nothing but a bundle of multiplications and summations which
-    may overflow during calculations.
-
-
-    This routine uses a scheme to test and scale the result output from
-    each FFT stage in order to fix the accumulation overflow.
-
-    The Input Data should be in Q13 format to get the highest precision.
-    At the end of each dragonfly calculation, a test for possible bit growth
-    is made, if bit growth is possible the Data is scale down back to Q13.
-
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    This function should provide a fixed point FFT for an input array
-    of size 64.

- Description: Fixed error in logic that determines whether there are enough
- bits available to conduct a search for the syncword.  The plus sign in
- the following condition should be a minus.
-
-    if (pInputStream->usedBits <

-
- The length of the syncword should subtract from the number of available

-
- Description:  Fixed condition when the end of file was found, unsigned
-   comparison produced a undesired search. Fixed by casting comparison

- FUNCTION DESCRIPTION
-
- This module scans the bitstream for a syncword of any length between 1 and 32.
- If certain bits in the syncword are to be ignored, that bit position should
- be set to 0 in both parameters *(pSyncword) and syncword_mask.  This allows
- for a syncword to be constructed out of non-contiguous bits.
-
- Upon finding the syncword's position in the bitstream, a value denoting the
- syncword's degree of deviance from being byte-aligned (byte_align_offset)
- is set in the structure pointed to by pInputStream.
- This is a value between 0 and 7.
-
- If no syncword is found, the function returns status == ERROR.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- "Don't care" bits must be set to '0' in both *(pSyncword) and syncword_mask.
-
- This function should not be called if there are less than
- (8 + syncword_length) bits in the buffer.

- REVISION HISTORY
-
- Date: 10/18/2002
- Description:
-            (1) Change the input arguments, no shifts information from
-                long_fft_rx4 is passed, only a single max is passed.
-            (2) Eliminate search for max, a fixed shift has replaced the
-                search for max with minimal loss of precision.
-            (3) Eliminated unused variables
-
- Date: 10/28/2002
- Description:
-            (1) Added comments per code review

-                type Int32 *
-
-    max       = Input, carries the maximum value of the input vector

-
-
- Local Stores/Buffers/Pointers Needed:

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
-    fwd_long_complex_rot() performs the pre complex rotation for the MDCT
-    for the case of long windows. It also performs digit reverse ordering of
-    the first and second halves of the input vector "Data_in", as well as
-    reordering of the two half vectors (following radix-2 decomposition)
-    Word normalization is also done to ensure 16 by 16 bit multiplications.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    fwd_long_complex_rot() should execute a pre-rotation by
-    exp(-j(2pi/N)(k+1/8)), digit reverse ordering and normalization

- FUNCTION DESCRIPTION
-
-    fwd_short_complex_rot() performs the complex rotation for the MDCT
-    for the case of short windows. It performs digit reverse ordering as well
-    word normalization to ensure 16 by 16 bit multiplications.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    fwd_short_complex_rot() should execute a pre-rotation by
-    exp(-j(2pi/N)(k+1/8)), digit reverse ordering and word normalization

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to remove instances of pow() and sqrt(), and
- optimized for inclusion in fixed-point version of decoder.
-
- Description:  Modified to include comments/optimizations from code review.
- Also, declared appropriate variables as type "const"
-
- Description:  Adopted strategy of "one q-format per sfb" strategy, which
- eliminated the array q-format from this function.  The q-format the
- random vector is stored in is now returned from the function.
-
- Description:  Completely redesigned the routine to allow a simplified
-        calculation of the adjusted noise, by eliminating the dependency
-        on the band_length. Added polynomial approximation for the
-        function 1/sqrt(power). Updated comments and pseudo-code
-
- Description:  Modified function description, pseudocode, etc.
-
- Description:
-    Modified casting to ensure proper operations for different platforms
-
- Description:
-    Eliminiated access to memory for noise seed. Now a local variable is
-    used. Also unrolled loops to speed up code.
-
- Description:
-    Modified pointer decrement to a pointer increment, to ensure proper
-    compiler behavior

- FUNCTION DESCRIPTION
-
- This function generates a vector of uniformly distributed random numbers for
- the PNS block.  The random numbers are each scaled by a scale_factor,
- defined in Ref(2) as
-
- 2^(scale_factor/4)
- ------------------
-  sqrt(N*MEAN_NRG)
-
- where N == band_length, and MEAN_NRG is defined as...
-
-         N-1
-         ___
-     1   \
-    ---   >    x(i)^2
-     N   /__
-         i=0
-
- And x is the unscaled vector from the random number generator.
-
- This function takes advantage of the fact that the portion of the
- scale_factor that is divisible by 4 can be simply accounted for by varying
- the q-format.
-
- The scaling of the random numbers is thus broken into the
- equivalent equation below.
-
- 2^(scale_factor%4)   2^(floor(scale_factor/4))
- ------------------ *
-  sqrt(N*MEAN_NRG)
-
-
- 2^(scale_factor%4) is stored in a simple 4-element table.
- 2^(floor(scale_factor/4) is accounted for by adjusting the q-format.
- sqrt(N*MEAN_NRG) is calculated and implemented via a polynomial approximation.
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall produce uniformly distributed random 32-bit integers,
- with signed random values of average energy equal to the results of the ISO
- code's multiplying factor discussed in the FUNCTION DESCRIPTION section.
-
- Please see Ref (2) for a detailed description of the requirements.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  Change to PV template, remove default config parameter,
-               move some functionality into get_prog_config().
-
- Description: Update per code review
-              1) Add parameter pScratchPCE
-              2) Change way ADIF_ID is read in.
-              3) Fix comments
-              4) ADD a test for status != SUCCESS in loop.
-
- Description: The ADIF_Header has now been delegated to the "scratch memory"
- union.  This change inside s_tDec_Int_File.h had to be reflected here also.
-
- Description: Updated the SW template to include the full pathname to the
- source file and a slightly modified copyright header.

- FUNCTION DESCRIPTION
-
- This function reads in the ADIF Header found at the front of ADIF streams.
- If the header is not found an error is returned. An ADIF header can contain
- from zero to sixteen program configuration elements (PCE). This function, and
- the rest of the library, saves and uses the first PCE found.

- REQUIREMENTS
-
- Function shall not use static or global variables.

- FUNCTION DESCRIPTION
-
- Acronym Definitions
- ADTS  Audio Data Transport Stream
- CRC   Cyclic Redundancy Code
-
- This function calls find_adts_syncword to find the next ADTS header.  Until
- three consistent headers have been read, the syncword used for detection
- consists of the 12-bit syncword and the 2-bit Layer.  After three consistent
- headers are read, the entire fixed header is used for a robust 28-bit
- syncword.
-
- Configuration information is then extracted from the bitstream.
-
- The bitstream information is packed as follows.
- Comments about the correct interpretation of these bits are contained within
- the code.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    audioObjectType = MP4 Audio Object Type for the current song. Only if
-                    this is set to LTP (MP4AUDIO_LTP) will long term
-                    prediction bits be retrieved. Data type
-                    tMP4AudioObjectType, which is an enumeration, which in
-                    turn is an Int.
-
-    pInputStream  = pointer to a BITS structure, used by the function getbits
-                    to provide data. This is the second parameter to this
-                    function to match its position in getbits().
-                    Data type pointer to BITS structure
-
-    common_window = field read in huffdecode, which tells whether information
-                    is shared between the left and right channel. Long term
-                    prediction (LTP) data is NOT shared even if its a common
-                    window, so this flag is needed to see if another set of
-                    LTP possibly needs to be read. If this flag is false,
-                    pSecondLTPStatus is not touched, it could be NULL if
-                    need be. Data type Bool, which is Int.
-
-    pWindowSequence = pointer to where the the window type of the current
-                    frame and channel should be placed, of data type
-                    WINDOW_SEQUENCE, which is Int. It can take on one
-                    of four values: ONLY_LONG_SEQUENCE, LONG_START_SEQUENCE,
-                    EIGHT_SHORT_SEQUENCE, LONG_STOP_SEQUENCE,
-
-    pWindowShape =  pointer to where the window shape for the current frame
-                    and channel should be placed, of data type WINDOW_SHAPE,
-                    which is Int. It can take on the one of these two values:
-                    SINE_WINDOW, KAISER_BESSEL_WINDOW. It is used in the
-                    "filterbank" section of decoding.
-
-    group         = array that holds the index of the first window in each
-                    group. Data type array of Int, eight elements.
-
-    p_max_sfb     = pointer to where the maximum number of scale factor bands
-                    for the current frame and channel will be placed. Data
-                    type of pointer to Int.
-
-    p_winmap      = array of pointers to all of the possible four window
-                    configurations. This parameter did not need to be pointers,
-                    and could be changed in the future. Data type array of pointers
-                    to FrameInfo structures, length 4.
-
-    pFirstLTPStatus = pointer to a structure where the first LTP
-                    information will be stored. It would be confusing and wrong
-                    to call this left LTP status since if common_window = FALSE,
-                    this function will be called twice - once for the left, once
-                    for the right. It could be done, but extra conditional code
-                    would need to be done.
-                    Data type pointer to LT_PRED_STATUS structure.
-
-    pSecondLTPStatus = pointer to where the right channel of LTP
-                    information will be stored only if common_window is non-zero.
-                    Data type pointer to LT_PRED_STATUS structure.
-
- Local Stores/Buffers/Pointers Needed: None.
-
- Global Stores/Buffers/Pointers Needed: None.
-
- Outputs:
-    status  = 0 implies no error occurred, non-zero otherwise.
-
- Pointers and Buffers Modified:
-    pInputStream contents are modified in such a way that the number of bits
-        read increases.
-    pWindowSequence contents are updated with the current window for this
-        frame and channel
-    group[] contents will be modified to grouping information. See getgroup
-        source code for a better description of what this is.
-    p_max_sfb contents will be updated with the maximum scale factor bands
-        for this frame and channel.
-    pFirstLTPStatus contents may be updated if the stream has long term
-        prediction information.
-    pSecondLTPStatus contents may be updated if common_window != 0 and LTP data
-        is present.
-
-
- Local Stores Modified: None
-
- Global Stores Modified: None
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function retrieves the individual channel stream (ICS) information
- from the bitstream. The information read for the current
- frame and channel is:
- - window sequence
- - window shape for use in the filter bank
- - number of scale factor bands
- - long term predication (LTP) information
- - grouping information
-
- This function does NOT support MPEG2 style AAC Frequency Domain Predictor,
- not to be confused with LTP (Long Term Prediction). If such data is found
- to be on the file an error is generated.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function is not to use static or global data.

- FUNCTION DESCRIPTION
-
- This function reads from the input stream to memory for a temporary
- program configuration element (PCE). If the PCE read is the first
- encountered it is saved. Or, if the tag of the PCE read matches the tag of
- the first PCE encounted, it is saved as well. This is a mechanism for
- changing the sampling rate.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall not use static or global variables.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description: Put into PV format
-
- Description: 1) Change loop to use pointers.
-              2) Rename to from get_nec_nc to get_pulse_data
-
- Description: Changes per code review
-              1) Fix pathname
-              2) Read in two fields to save call to getbits
-              3) Change how pPulseInfo->number_pulse is stored.
-
- Description: Placed typecast to Int in places where UInt->Int
-
- Description: Replace some instances of getbits to get9_n_lessbits
-              when the number of bits read is 9.
-
- Who:                                  Date:

-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-     pInputStream = pointer to a BITS structure, used by the function getbits
-                   to provide data. Data type pointer to BITS structure
-
-     pPulseInfo   = pointer to pulse data structure to be filled with data
-                    concerning pulses in the frequency domain.
-                    Data type pointer to PulseInfo
-
- Local Stores/Buffers/Pointers Needed: None
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
-     status       = return value, zero signifies success, non-zero otherwise.
-                    Presently this function only returns a success, error
-                    checking may be added later.
-                    Data type Int.
-
- Pointers and Buffers Modified:
-
-    pPulseInfo contents are updated with pulse information. Specifically,
-    pPulseInfo->number_pulse with the number of pulses found, and
-    pPulseInfo->pulse_start_sfb is set to the first scale factor band.
-    Then pPulseInfo->pulse_offset and pPulseInfo->pulse_amp are filled
-    with data. For these array, only the number of pulses defined will be
-    set, those values beyond the number of pulses will retain their previous
-    value and should not be read from.
-    Note: The value in pPulseInfo->number_pulse is different by a value of
-          one from the original ISO code.
-
-    pInputBuffer contents are updated to the next location to be read from
-        the input stream.
-
- Local Stores Modified: None
-
- Global Stores Modified: None
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function fills in the pulse data structure with information to be used
- later for restoring pulses in the spectrum.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall not use global or static variables.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  Brought code in-line with PV standards.  Some minor
-               optimizations (count-down for loops, etc.) were made.
-
- Description:  Made cosmetic changes as suggested during review.  Also,
- changed calculation of s_mask and n_mask from table-based to being
- calculated based on res_index.  Also, the flag coef_res was changed
- from having a range of [3,4] to having a range of [0,1], which corresponds
- exactly with the true value that is passed via the bitstream.
-
- Description:  Modified to use more efficient TNS memory structure.
-
- Description: Updated to reflect more efficient usage of memory by the TNS
- filters.
-
- Description: Updated the SW template to include the full pathname to the
- source file and a slightly modified copyright header.
-
- Description: Moved pInputStream to be the 2nd parameter, for a slight
- optimization on some platforms.
-
- Description: Moved pSfbTop outside of the loops, since its value does
- not change.
-
- Description: Replace some instances of getbits to get1bits
-              when only 1 bit is read.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    FrameInfo *pFrameInfo
-        Pointer to structure that holds information about each block.
-        (long block flag,
-         number of subblocks,
-         scalefactor bands per subblock, etc.)
-
-    BITS *pInputStream
-        Pointer to a BITS structure that is
-        passed on to function getbits to pull information from the bitstream.
-
-    TNS_Frame_info *pTnsFrameInfo
-        Pointer to filter data structure - to be populated by this function.
-
- Local Stores/Buffers/Pointers Needed:
-    None
-
- Global Stores/Buffers/Pointers Needed:
-    None
-
- Outputs:
-    None
-
- Pointers and Buffers Modified:
-    TNS_frame_info *pTnsFrameInfo
-
-    pTnsFrameInfo->n_filt = Number of tns filters to be applied to the data.
-
-    pTnsFrameInfo->filt[]->order = The order of each individual TNS filter.
-
-    pTnsFrameInfo->filt[]->coef_res = The resolution of the filter coefficients
-
-    pTnsFrameInfo->filt[]->start_band = start of spectral band
-
-    pTnsFrameInfo->filt[]->stop_band = end of spectral band
-
-    pTnsFrameInfo->filt[]->coef[] = Each filter's coefficients are filled with
-    data read from the input bitstream.
-
-    pTnsFrameInfo->filt[]->direction = A flag is set for each TNS filter.
-
-    If the direction flag (on the bitstream) = 0, then the filter
-    is applied to the block of spectral data in normal (upward) fashion.
-
-    If the direction flag (on the bitstream) = 1, then the filter
-    is applied in a reverse (downward) fashion.
-    (Starting with the last element in the block of data.)
-
-    The value stored in filt[]->direction maps the values [0,1] to [1,-1] for
-    a more intuitive storage of this flag's meaning.

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function reads the TNS filter information from the bitstream, and stores
- the filter order, LPC coefficients, and the number of TNS filters to
- be applied in the structure TNS_frame_info.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This code should match the ISO code in functionality, with the exception
- that coef_res has range of [0,1] (PV code) instead of [3,4] (ISO code)
-
- coef_res is only used by tns_decode_coef.

- FUNCTION DESCRIPTION
-
- This function reads the window grouping information associated with an
- Individual Channel Stream (ICS). If the window sequence is
- EIGHT_SHORT_SEQUENCE, scalefactor grouping information is transmitted. If a
- set of short windows form a group then they share scalefactors, intensity
- positions and PNS information. The first short window is always a new group
- so no grouping bit is transmitted. Subsequent short windows are in the same
- group if the associated grouping bit is 1. A new group is started if the
- associated grouping bit is 0.
- The pointer pGroup points to an array that stores the first window index
- of next group. For example, if the window grouping is:
-
- window index:    |  0  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |
- grouping    :    |<-   0   ->|  1  |<-    2        ->|<-   3   ->|
-
- Then:
-
-    group[]  :    |     2     |  3  |        6        |     8     |
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function should replace the contents of the array pointed to by pGroup
- with the first window indexes of groups starting from the second group.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables
-
- Description: Remove pass-in parameter global_gain, define it on stack.
-
- Description: (1) Modified to bring in-line with PV standards
-              (2) Modified pass in parameters
-              (3) Removed multiple returns, removed some if branch
-              (4) Replace for loop with pv_memset
-
- Description: Remove prstflag, fix copyright.
-
- Description: Fix pseudo-code
-
- Description: Remove lpflag from get_ics_info
-
- Description: (1) Removed widx, therefore, pChVarsWin is eliminated from
-                  pass in parameter
-
- Description: merged the above changes from Michael and Wen
-
- Description: Removed initialization of "pTnsFrameInfo->num_subblocks" since
- this element was removed from that structure, as a part of
- rearchitecting the TNS routines to use memory more efficiently.
-
- Description:
- (1) Added #include of "e_HuffmanConst.h"
-     Previously, this function was relying on another include file
-     to include "e_HuffmanConst.h"
-
- (2) Updated the copyright header.
-
- (3) Added #include of <stdlib.h> for NULL macro definition.
-
- Description:
- (1) Removed the first parameter to getics.c  This extra
-     FrameInfo was not needed, the contents of winmap can be used.
- (2) Removed the memcpy of the data from winmap to the temporary
-     FrameInfo.
-
- Description: Replace some instances of getbits to get1bits
-              when only 1 bit is read.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-               Replaced for-loop style memory initialization with memset()
-
- Description: (1) Modified to bring code in-line with PV standard
-              (2) Removed multiple returns, Replaced multiple 'if's with
-                  switch
-
- Description: (1) Modified per review comments
-              (2) increment pointer pMask after memset
-
- Description: Make the maximum number of bits requested from getbits
-              become a constant.
-
- Description: Typecast 1 to UInt32 for bitmask to avoid masking on a 16-bit
-              platform
-
- Description: Replace some instances of getbits to get9_n_lessbits
-              when the number of bits read is 9 or less.

-
- Outputs:
-    mask_present = 0    (no Mid/Side mixed)
-                   2    (Mid/Side mixed present for entire frame)
-                   1    (Mid/Side mixed information read from bitstream)
-                   -1   (invalid mask_present read from bitstream)
-
- Pointers and Buffers Modified:
-    pMask   contents replaced by MS information of each scalefactor band
-

-    None
-
- Global Stores Modified:
-    None
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function reads the Mid/Side(MS) mask information from the input
- bitstream. If the mask_present field is equal to 2, the mask bits is set to
- 1 for the entire frame. If mask_present has a value of 0, the function
- returns 0, If mask_present is set to 1, the Mid/Side(MS) information is
- read from the input stream. When mask_present is 3, an error code (-1) is
- generated.
- The Mid/Side(MS) information is later used for mixing the left and right
- channel sounds. Each scalefactor band has its own MS information.
-
- (ISO comments: read a synthesis mask,  read a synthesis mask uses
-                EXTENDED_MS_MASK and grouped mask )
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall replace the contents of pMask with the MS information
- of each scalefactor band

-   shifted to meet the maximum codelength. Example, max codelength is
-   10, the codeword with lenth 3 will left shift by 7.
-   The binary values of after the shift are sorted.
-   Then the sorted table is divided into several partition.
-   At the VLC decoding period, input is read in at max codelenght.
-   The partition is decided using if-else logic.
-   Inside each partition, a look-up table is used to map the input value
-   to a correct symbol. Table entries can appear to be repeated according
-   to the humming distance between adjacent codewords.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  Change variable names for clarity,
-               change variables 'base', 'sect_len_inc', and 'esc_val' to
-               UChar type.
-
- Description:  Add "if ((pSect[-1] % sfb_per_win) > max_sfb)" statement to
-               detect the error condition.
-               add more white space.
-
- Description: eliminated "pSect[-1]%sfb_per_win" operation
-
- Description: eliminated "pSect[-1]%sfb_per_win" operation
-
- Description: (1) Pass in SectInfo pSect
-              (2) put BITS *pInputStream as second parameter
-
- Description:  Fix a failure for thrid party AAC encoding.
-               The problem came when the total and the
-               maximun number of active scale factor bands do not coincide.
-               This is a rare situation but produces a problem when decoding
-               encoders that tolerate this.
-
- Description: Replace some instances of getbits to get9_n_lessbits
-              when the number of bits read is 9 or less and get1bits
-              when only 1 bit is read.

- FUNCTION DESCRIPTION
-
- Background knowledge: 1024(960) coef's are separated into several sections,
- each section is encoded with one single Huffman codebook, and each section
- has a length of multiples of sfb.
-
- max_sfb <= sfb_per_win <= tot_sfb
- tot_sfb = total number of scalefactor bands in one frame (1024 coefs)
-
- This function reads the codebook index and section boundaries (expressed
- in number of sfb) from the input bitstream, store these information in
- *pSect, and return the number of sections been detected. Returns 0 if there
- is an error.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function should fill the array *pSect with section Huffman codebook
- indexes and section boundaries

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  Change variable types.
-
- Description:  (1) Modified to bring in-line with PV standards.
-               (2) Eliminated global_gain on stack,
-                   getics() has to define this parameter on its stack.
-               (3) Eliminated multiple returns
-               (4) Altered return logic of getics()
-               (5) Convert Real coef -> Int32 coef
-               (6) Move BITS *pInputStream to 2nd parameter of huffdecode.c
-                   and getics.c
-               (7) Pass pFrameInfo per channel, because two channels can have
-                   different windows
-
- Description: (1) Eliminated function call to chn_config
-              (2) Eliminate widx calculation
-              (3) copy channel info from left to right when common_window
-                  is enabled
-              (4) add error checking of getmask return value
-
- Description:  Change default_position to current_program
-
- Description:  Remove prstflag
-
- Description:  Modify call to get_ics_info
-
- Description:  Modified so getmask is NOT called if the status returned
- from get_ics_info indicates an error.
-
- Description:
- (1) Added include of "e_ElementId.h"
-     Previously, this function was relying on another include file
-     to include e_ElementId.h
-
- (2) Updated the copyright header.
-
- Description:  Modified to include usage of the new "shared memory" structures
- defined in s_tDec_Int_File.h and s_tDec_Int_Chan.h
-
- Description:
- (1) Updated to reflect the fact that the temporary FrameInfo used by getics.c
- was moved into the region of memory shared with fxpCoef.
-
- Description:
- (1) Removed first parameter to getics.  The temporary FrameInfo was
-     unnecessary.
-
- Description: Replace some instances of getbits to get9_n_lessbits
-              when the number of bits read is 9 or less and get1bits
-              when only 1 bit is read.
-
- Description: Relaxed tag verification. Some encoder do not match the tag
-              to the channel ID (as the standard request to differentiate
-              different channel), in our wireless work, with only mono
-              or stereo channel, this become restrictive to some encoders

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description: (1) Modified with new templates,
-              (2) Modified variable names for clarity
-              (3) adjusted variables of "for loop"

-
- Description: (1) Change return logic: 0 if success, 1 if error
-              (2) Define SectInfo structure to store section codebook index
-                  and section boundary
-              (3) Substitute "switch" with "if- else if"
-              (4) move BITS *pInputStream to second pass-in parameter
-              (5) pass in huffBookUsed[] to save stack size
-
- Description: (1) Remove pass in parameter Hcb pBook
-
- Description: Use binary tree search in decode_huff_cw_binary
-
- Description: Use decode_huff_scl function.

- FUNCTION DESCRIPTION
-
- This function first reads the Huffman codebook index of all sections within
- one Frame. Then, depending on the huffman codebook index of each section,
- the function decodes the scalefactors, and/or intensity positions
- (INTENSITY_HCB, INTENSITY_HCB2), and/or noise energy (NOISE_HCB)
- for every scalefactor band in each section.
- The function returns 0 upon successful decoding, returns 1 if error.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function should replace the content of the array pFactors with the
- decoded scalefactors and/or intensity positions and/or noise energy

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description: (1) Modified to keep in-line with PV standards
-              (2) Eliminated "continue" in if(sect_cb==ZERO_HCB||...)
-
- Description: (1) Use SectInfo *pSect
-              (2) Convert 'Real' to 'Int32', float -> fixed-point
-              (3) move BITS *pInputStream to second parameter
-              (4) pass in quantSpec and tmp_spec, scratch shared with hufffac
-              (5) pass in FrameInfo *pLongFrameInfo, eliminate only_long_info
-
- Description: (1) Eliminate parameter Hcb *book, because of eliminating
-                  function 'hufftab.c', Hcb hcbbook defined as a
-                  const structure in 'hcbtables.h'.
-              (2) Replace three nested 'for' loops with a for-while loop in
-                  the rescaling part.
-              (3) Change esc_iquant-> esc_iquant_fxp, call esc_iquant_fxp()
-                  by sfb
-
- Description: Cleaned up include files.
-
- Description:  Correct definition of stack variable "scale".
-        It was defined as Int, but it receives an UInt value,
-        this present a problem when Int is 16 bits and
-        the sign bit is not interpreted correctly. This does not
-        shows for 32-bit implementations. This problem manifest itself
-        as a flipping sign on some spectral coefficients (the ones
-        multiplied by 0x8000).
-
- Description: Typecast b_low and b_high to 32-bits before multiplication, this
-              assures propoer compilation on a 16-bit platform (TI-C55x)
-
- Description: Modified to speed up decode_huff_cw
-
- Description: pass codebook index to decode_huff_cw, delete pointer to Huffman
-              structure
-
- Description: keep memset to quantSpec, remove memset to temp_spec
-
- Description: Modified per review comments
-
- Description: Use Binary tree search in decode_huff_cw_binary
-
- Description: Modified per review comments
-              (1) delete unused codes
-
- Description: (1) Change the interface to decode huffman codeword.
-              (2) Move the scaling inside the inverse quantization.
-              (3) Change scaling factor accuracy to 10 bits.
-
- Description:
-              (1) delete unused variable max_fac
-
- Description: Addresses of huffman tables are now found by means of a
-              switch statement, this solve linking problem when using the
-              /ropi option (Read-only position independent) for some
-              compilers

- FUNCTION DESCRIPTION
-
- This function first reads the section info (codebook and boundary), then
- decode the spectral coefficients if a spectral codebook is used.
- If necessary, get the sign bits, ESC value or the NEC_pulse data. In case of
- short window sequences, the decoded data is de-interleaved before
- multiplied by scalefactors.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function should set the content of the array 'coef' with the inverse
- quantized and rescaled value of spectral coefficients.

- FUNCTION DESCRIPTION
-
-    The IMDCT is a linear orthogonal lapped transform, based on the idea of
-    time domain aliasing cancellation (TDAC).
-    IMDCT is critically sampled, which means that though it is 50% overlapped,
-    a sequence data after IMDCT has the same number of coefficients as samples
-    before the transform (after overlap-and-add). This means, that a single
-    block of IMDCT data does not correspond to the original block on which the
-    IMDCT was performed. When subsequent blocks of inverse transformed data
-    are added (still using 50% overlap), the errors introduced by the
-    transform cancels out.Thanks to the overlapping feature, the IMDCT is very
-    useful for quantization. It effectively removes the otherwise easily
-    detectable blocking artifact between transform blocks.
-
-    N = twice the length of input vector X
-    y = vector of length N, will hold fixed point IDCT
-    p = 0:1:N-1
-
-                    2   N/2-1
-            y(p) = ---   SUM   X(m)*cos(pi/(2*N)*(2*p+1+N/2)*(2*m+1))
-                    N    m=0
-
-    The window that completes the TDAC is applied before calling this function.
-    The IMDCT can be calculated using an IFFT, for this, the IMDCT need be
-    rewritten as an odd-time odd-frequency discrete Fourier transform. Thus,
-    the IMDCT can be calculated using only one n/4 point FFT and some pre and
-    post-rotation of the sample points.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  Pass eight_short_info and the array 'sfbwidth128'.
-               Change function arguments' names for clarity
-
- Description:  move sfb definitions to "sfb.h", and "sfb.c", eliminated
-               the function "huffbookinit.c"
-
- Description:  Remove initialization of the never used array,
-               pFrameInfo->group_offs
-
- Description:
- (1) Changed "stdinc.h" to <stdlib.h> - this avoids linking in the math
- library and stdio.h.  (All for just defining the NULL pointer macro)
-
- (2) Updated copyright header.
-
- Description: Updated the SW template to include the full pathname to the
- source file and a slightly modified copyright header.
-
- Description: Addresses of constant vectors are now found by means of a
-              switch statement, this solve linking problem when using the
-              /ropi option (Read-only position independent) for some

- REVISION HISTORY
-
- Description: Modified per review comments.
-
- Description: Noticed that the code could be more efficient by
- using some other method for storing the sign.  The code was changed to
- use a signed Int to store the table, and an adjustment of the q-format to
- reflect the difference between the data being shifted by 16 and the table
- being stored in q-15 format.
-
- Description: Updated pseudocode
-
- Description: When the multiplication of two 16-bits variables is stored in
-              an 32-bits variable, the result should be typecasted explicitly
-              to Int32 before it is stored.
-              *(pCoefRight++) = (Int32) tempInt2 * multiplier;

- FUNCTION DESCRIPTION
-
- This function applies Intensity Stereo, generating data on the right channel
- that is derived from data on the Left.  A scalefactor is applied using the
- following formula...
-
- RightCh = LeftCh*0.5^(scalefactor/4)
-
- This function works for one scalefactor band, which may belong to a group.
- (i.e. the same scalefactor band repeated across multiple windows belonging
-  to one group.)
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- codebook must be either INTENSITY_HCB or INTENSITY_HCB2 when this function
- is called.
-
- ms_used must be 1 when TRUE, 0 when FALSE.
-
- wins_in_group falls within the range [1-8]

- REVISION HISTORY
-
- Description:  Change the input argument, no shifts information from long fft_rx4
-               , do not have to check for shifts.
-
- Date: 10/18/2002
- Description:
-            (1) Change the input argument, only a single max is passed.
-            (2) Eliminate search for max, a fixed shift has replaced the
-                search for max with minimal loss of precision.
-            (3) Eliminated unused variables
-
- Date: 10/28/2002

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-
-    Data_in   = Input vector (sized for long windows
-                TWICE_INV_LONG_CX_ROT_LENGTH), with time domain samples
-                type Int32 *
-
-    Data_out  = Output vector with a post-rotation by exp(j(2pi/N)(k+1/8)),
-                (sized for long windows TWICE_INV_LONG_CX_ROT_LENGTH)
-                type Int32 *
-
-    max       = Input, carries the maximum value of the input vector

-                type Int32
-
-
- Local Stores/Buffers/Pointers Needed:
-    None
-
- Global Stores/Buffers/Pointers Needed:

-
- Outputs:
-    exp = shift factor to reflect signal scaling
-
- Pointers and Buffers Modified:
-    Results are return in "Data_out"
-

-
- Global Stores Modified:
-    None
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
-    inv_long_complex_rot() performs the complex rotation for the inverse MDCT
-    for the case of long windows. It also performs digit reverse ordering of
-    the first and second halves of the input vector "Data_in", as well as
-    reordering of the two half vectors (following radix-2 decomposition)
-    Word normalization is also done to ensure 16 by 16 bit multiplications.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    inv_long_complex_rot() should execute a post-rotation by
-    exp(-j(2pi/N)(k+1/8)), digit reverse ordering and word normalization

-            (1) Change the input argument, only a single max is passed.
-            (2) Eliminate search for max, a fixed shift has replaced the
-                search for max with minimal loss of precision.
-            (3) Eliminated unused variables
-
- Date: 10/28/2002
- Description:
-            (1) Added comments per code review
-            (2) Eliminated hardly used condition on if-else (exp==0)

- FUNCTION DESCRIPTION
-
-    inv_short_complex_rot() performs the complex rotation for the inverse MDCT
-    for the case of short windows. It performs digit reverse ordering as well
-    word normalization to ensure 16 by 16 bit multiplications.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    inv_short_complex_rot() should execute a post-rotation by
-    exp( j(2pi/N)(k+1/8)), digit reverse ordering and word normalization

- REVISION HISTORY
-
- Description: Made changes based on comments and experiment results.
-
- Description: Passed in buffer sizes based on review comments and prototype
-              agreements.
-
- Description: 1. Passed in "weight_index" instead of "weight".
-              2. Added weight table.
-
- Description: 1. Removed some passed in buffer size variables since they are
-                 not used for long window.
-              2. Modified comments format.
-
- Description:
-    Modified casting to ensure proper operations for different platforms
-
- Description:
-    Implemented circular buffer techniques, which save 4096 memmoves per
-    frame.
-
- Description:
-    Implemented some optimizations found during the code review of this
-    module.  The optimizations related to the rules on the range of
-    ltp_buffer_index and num_samples, which allows for a simpler
-    code construct to be used in the processing of the predicted samples.
-
- Description:
-    Add max calculation on the filter implementation, this to eliminate
-    function buffer_adaptation() on the time to frequency transformation.
-    Function interface changed. It now return the amount of shifting needed
-    to garb only the top 16 MSB.
-
- Description:
-     Replace clearing memory with for-loop with pvmemset function
-
- Description:
-
-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    win_seq = type of window sequence (WINDOW_SEQUENCE).
-
-    weight_index = index (Int) of LTP coefficient table for all windows in
-                   current frame.
-
-    delay = buffer (Int) containing delays for each window.
-
-    buffer = history buffer (Int16) containing the reconstructed time domain
-             signals of previous frames.
-
-    buffer_offset = value (Int) that indicates the location of the first
-                    element in the LTP circular buffer.  (Either 0 or 1024)
-
-    time_quant    = filterbank buffer (Int32) This buffer is used by the
-                    filterbank, but it's first 1024 elements are equivalent
-                    to the last 1024 elements in the conventionally
-                    implemented LTP buffer.  Using this buffer directly avoids
-                    costly duplication of memory.
-
-    predicted_samples = buffer (Int32) with length of 2048 to hold

- FUNCTION DESCRIPTION
-
- Long term prediction (LTP) is used to reduce the redundancy of a signal
- between successive coding frames. This function performs prediction by
- applying 1-tap IIR filtering to calculate the predicted time domain
- signals of current frame from previous reconstructed frames stored in
- time domain history buffer.
-
- The equation used for IIR filter is as following.
-
-            y(n) = weight * x(n - delay)
-
-    where   y(n) ----- predicted time domain signals
-            x(n) ----- reconstructed time domain signals
-            weight ----- LTP coefficient
-            delay ----- optimal delay from 0 to 2047

- REVISION HISTORY
-
- Description: Made the following changes based on the review comments.
-              1. Separated "shift_factor>=0" on line 395 to "shift_factor>0"
-                 and "shift_factor=0" two cases.
-              2. Added comments on line 393 to explain why factor 2 is being
-                 used to calculate shift_factor.
-              3. Added comments for short window implementation.
-              4. Changed "*(pPredicted_spectral++) = *pPredicted_spectral>>2"
-                 to "*(pPredicted++)>>=2" although they are the same.
-              5. Changed pseudo code "X+=Y" to "X=X+Y".
-              6. Fixed ending comment of "for" loop.
-              7. Passed in the size of the array and deleted some of the
-                 include files.
-
- Description: Unroll the loops.
-
- Description: Changed index "wnd" in previous line 584 with "wnd_offset"
-              and made other correspondent changes to the code.
-
-
- Description: Based on Ken's suggestion, modified the function with the
-              passing-in Q format as scalefactor band basis in order to
-              simplify TNS block functions.
-
- Description: Optimization.
-
- Description: Made changes based on review comments.
-              1. Changed misspellings.
-              2. Changed win_sfb_top[] from two dimensional array to one
-              dimensional array and correspondently changed the code.
-              3. Changed function prototype to remove some redundant
-              informations.
-              4. Fixed the adjusting Q format part code.
-              5. Fixed lines 825, 826 with correct updating pointers.
-
- Description: Due to TNS and LTP Q format issue, added code to adjust
-              predicted_spectral() to maximum resolution before perform
-              long term synthesis.
-
- Description: Modified based on review comments.
-
- Description: Changed "max" data type from UInt to UInt32.
-
- Description: Changed so that nothing is done for the case of "all zero"
- data coming from the output of Trans4m_time_2_freq. Also, included more
- efficient calculation of the abs(x).  And, I updated the pseudocode.
-
- Description: Use an auxiliary variable temp, to avoid using the same
-    pointer and a post-increment pointer in the same line. This may not
-    work with all compilers.

- FUNCTION DESCRIPTION
-
- This function performs long term synthesis using transmitted spectral
- coeffients or errors and predicted spectral components.
-
- Long term synthesis is part of long term prediction (LTP) which is used to
- reduce the redundancy of a signal between successive coding frames. The
- functionality of long term synthesis is to reconstruct the frequency domain
- spectral by adding the predicted spectral components and the transmitted
- spectral error when prediction is turned on.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Modified to pass variables by reference to eliminate use
-               of global variables.
-
- Description:  First round of optimizations.
-
- Description:  pInputStream is now the 2nd parameter to this function.
-
- Description:  Changed to work with MT's new get_ics_info.c function, which
- only calls lt_decode if LTP is enabled.  This removes one grab from the
- bitstream and one "if" from this code.  Also, changed setting of weight.
- Now, rather than setting the actual weight, I only set the index into
- a table in this function.
-
- Description: Replace some instances of getbits to get9_n_lessbits
-              when the number of bits read is 9 or less and get1bits
-              when only 1 bit is read.

- FUNCTION DESCRIPTION
-
-    The MDCT is a linear orthogonal lapped transform, based on the idea of
-    time domain aliasing cancellation (TDAC).
-    MDCT is critically sampled, which means that though it is 50% overlapped,
-    a sequence data after MDCT has the same number of coefficients as samples
-    before the transform (after overlap-and-add). This means, that a single
-    block of MDCT data does not correspond to the original block on which the
-    MDCT was performed. When subsequent blocks of data are added (still using
-    50% overlap), the errors introduced by the transform cancels out.
-    Thanks to the overlapping feature, the MDCT is very useful for
-    quantization. It effectively removes the otherwise easily detectable
-    blocking artifact between transform blocks.
-    N = length of input vector X
-    X = vector of length N/2, will hold fixed point DCT
-    k = 0:1:N-1
-
-                        N-1
-            X(m) =  2   SUM   x(k)*cos(pi/(2*N)*(2*k+1+N/2)*(2*m+1))
-                        k=0
-
-
-    The window that completes the TDAC is applied before calling this function.
-    The MDCT can be calculated using an FFT, for this, the MDCT needs to be
-    rewritten as an odd-time odd-frequency discrete Fourier transform. Thus,
-    the MDCT can be calculated using only one n/4 point FFT and some pre and
-    post-rotation of the sample points.
-
-    Computation of the MDCT implies computing
-
-        x  = ( y   - y        ) + j( y       +  y       )
-         n      2n    N/2-1-2n        N-1-2n     N/2+2n
-
-    using the Fast discrete cosine transform as described in [2]
-
-    where x(n) is an input with N points
-
-    x(n) ----------------------------
-                                     |
-                                     |
-                    Pre-rotation by exp(j(2pi/N)(n+1/8))
-                                     |
-                                     |
-                              N/4- point FFT
-                                     |
-                                     |
-                    Post-rotation by exp(j(2pi/N)(k+1/8))
-                                     |
-                                     |
-                                      ------------- DCT
-
-    By considering the N/2 overlap, a relation between successive input blocks
-    is found:
-
-        x   (2n) = x (N/2 + 2n)
-         m+1        m
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    This function should provide a fixed point MDCT with an average
-    quantization error less than 1 %.

- REVISION HISTORY
-
- Description:  Eliminated pointer dependency ( pData_1) on Buffer address.
-               Modified for-loop to countdown loops.
-
- Description:  No shift information going in/out from fft_rx4_long.
-
- Description:
-            (1) Increased precision on the radix 2 fft coeff. (from Q10 to Q12)
-            (2) Increased precision on the input (from 0.5 to 1.0).
-            (3) Eliminated hardly used condition (exp = 0).
-            (4) Change interface to fft_rx4_long, so now the same function is
-                used for forward and inverse calculations.

- FUNCTION DESCRIPTION
-
- This module applies the formula for M/S coding to one grouped scalefactor
- band.  The ISO code has a similar function which applies M/S coding to an
- entire frame.
-
- It is the calling function's responsibility to check the map_mask array, which
- is filled by the function getmask.  If a scalefactor band is identified as
- using M/S stereo, the coefficients in that array are calculated using
- the following formula...
-
- TempLeft = LeftCoefficient;
-
- LeftCoefficient  = LeftCoefficient  + RightCoefficient;
- RightCoefficient = TempLeft         - RightCoefficient;
-
- This function should be inlined if the compiler supports C99 inlining,
- as this short function is only called by sfb_tools_ms().
- Therefore, inlining will not increase the code size.

- FUNCTION DESCRIPTION
-
- This function derives noise from the left channel.  The PNS tool is assumed
- to have been used on the same scalefactor band on the left channel.  The
- noise on the left/right channels are not necessarily of the same amplitude,
- and therefore have separate scalefactors.  The noise is thus scaled by the
- difference between the two transmitted scalefactors.  This scaling is done
- in fixed-point using a constant 4-element table.

- FUNCTION DESCRIPTION
-
- This function steps through all of the scalefactor bands, looking for
- either PNS or IS to be enabled on the right channel.
-
- If the codebook used is >= NOISE_HCB, the code then checks for the use
- of Huffman codebooks NOISE_HCB, INTENSITY_HCB, or INTENSITY_HCB2.
-
- When a SFB utilizing the codebook NOISE_HCB is detected, a check is made to
- see if M/S has also been enabled for that SFB.
-
- If M/S is not enabled, the band's spectral information is filled with
- scaled random data.   The scaled random data is generated by the function
- gen_rand_vector.  This is done across all windows in the group.
-
- If M/S is enabled, the band's spectral information is derived from the data
- residing in the same band on the left channel.  The information on the right
- channel has independent scaling, so this is a bit more involved than a
- direct copy of the information on the left channel.  This is done by calling
- the inline function pns_corr().
-
- When a SFB utilizing an intensity codebook is detected, the band's spectral
- information is generated from the information on the left channel.
- This is done across all windows in the group.  M/S being enabled has the
- effect of reversing the sign of the data on the right channel.  This code
- resides in the inline function intensity_right().

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Brought code in-line with PV standards.
-               Merged PNS and Intensity blocks into one function.
-               Modified routine to interface with a fixed-point implementation.
-               Modified variable names for clarity.
-               Improved for-loop structure that was previously checking
-               the codebook used in each scale factor band multiple times.
-
- Description:  Added some comments for clarity.
-
- Description:  Changed strategy for q-format.  Q-format for SFBs should not
- be grouped.
-
- Description: Function had to be modified to obey new interpretation of the
- sfb_prediction_used flag.  LTP takes precedence, and PNS should not be
- executed when a collision occurs between these two tools.
-
- Description:
- (1) Added flag "ltp_data_present"
- (2) Where feasible, I updated the code to resemble right_ch_sfb_tools_ms.c
-     Just for conformance, readability.
-
- Description: Added include file - "e_huffmanconst.h"
-
- Description: The same "Factors" pointer indexing problem that existed in
- right_ch_sfb_tools_ms also existed here in pns_left.c
-
- Description:  Modified how groups and windows are handled, as the multigroup
- case was not correct

- FUNCTION DESCRIPTION
-
- The function steps through each scalefactor band in the group, and
- checks for the use of Huffman codebook NOISE_HCB.
-
- When a SFB utilizing NOISE_HCB is detected, the band in every window in the
- group has its spectral information filled with scaled random data.
-
- The scaled random data is generated by the function gen_rand_vector.
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This module shall replace bands that were encoded with the Huffman codebook
- NOISE_HCB with random noise as returned from gen_rand_vector().  The result
- shall be perceptually indistinguishable from the result obtained by the
- ISO decoder.

- FUNCTION DESCRIPTION
-
-    Does Hybrid analysis:
-
-        Get higher frequency resolution in the lower QMF subbands
-        creating sub-subbands. This is done by low frequency filtering.
-        Lower QMF subbands are further split in order to obtain a higher
-        frequency resolution, enabling a proper stereo analysis and synthesis
-        for the lower frequencies.
-        Two hybrid are defined. Both filters have length 13 and a delay of 6.
-        In this implementation, the symmetry of the filters helps to simplify
-        the design.
-
-
-   Increase Freq. Resolution

-
-                      Variable is named (pLongFrameInfo) because this function

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function adds pulses to defined ranges of coefficients in the window,
- for the case of LONG windows.  The pulses are unsigned, so
- negative coefficients subtract the pulse, and positive coefficients add it.
- (The ampltiude of the coefficient is always increased by the pulse)
-
- A maximum of 4 coefficients may be modified by a pulse, and these
- coefficients must all occur in the same scalefactor band.
-
- The number of pulse-encoded coefficients to be processed by this function
- is communicated to this function via pPulseInfo->number_pulse
-
- This value is equal to the actual number of pulses - 1.
- (e.g if pPulseInfo->number_pulse == 0, one pulse is assumed)
- This function must not be called if no pulse encoded data exists.
- The function assumes that at least one pulse exists.
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This module shall correctly add transmitted pulse(s) to the correct
- coefficients in a LONG window.

- REVISION HISTORY
-
- Description:  Removed errant semicolons from #define statements
-
- Description:
-        1. Modified ifndef STD_TYPE_DEFS_H with
-           #ifndef PV_AUDIO_TYPE_DEFS_H to avoid double definition
-               if file was already included
-        2. Merged cai if-def structures and C++ definition
-            3. Updated copyright notice
-
- Description:  Added dependency on OSCL libraries
-
- Description:

-
- This file was derived from a number of standards bodies. The type
- definitions below were created from some of the best practices observed

- ANSI C environment limits.h is expected to always be present and contain
- the following definitions:

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    pExt = pointer to the external interface structure. See the file
-           PVMP4AudioDecoder_API.h for a description of each field.
-           Data type of pointer to a tPVMP4AudioDecoderExternal
-           structure.
-
-           pExt->pInputBuffer: pointer to input buffer containing input
-                               bitstream
-
-           pExt->inputBufferCurrentLength: number of bytes in the input buffer
-
-           pExt->inputBufferUsedLength: number of bytes already consumed in
-                                        input buffer
-
-           pExt->remainderBits: number of bits consumed in addition to
-                                pExt->inputBufferUsedLength
-
-    pMem = void pointer to hide the internal implementation of the library
-           It is cast back to a tDec_Int_File structure. This structure
-           contains information that needs to persist between calls to
-           this function, or is too big to be placed on the stack, even
-           though the data is only needed during execution of this function
-           Data type void pointer, internally pointer to a tDec_Int_File
-           structure.
-
- Local Stores/Buffers/Pointers Needed: None
-           (The memory set aside in pMem performs this task)
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
-     status = 0                       if no error occurred
-              MP4AUDEC_NONRECOVERABLE if a non-recoverable error occurred
-              MP4AUDEC_RECOVERABLE    if a recoverable error occurred.
-              Presently a recoverable error does not exist, but this
-              was a requirement.
-
-
- Pointers and Buffers Modified:
-    pMem contents are modified.
-    pExt: (more detail in the file PVMP4AudioDecoder_API.h)
-    inputBufferUsedLength - number of array elements used up by the stream.
-    remainderBits - remaining bits in the next UInt32 buffer
-    samplingRate - sampling rate in samples per sec
-    encodedChannels - channels found on the file (informative)
-    frameLength - length of the frame
-
- Local Stores Modified: None.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Pulled in loop structure from console.c, so that this function
-               now decodes all frames in the file.
-
-               Original program used several global variables.  These have been
-               eliminated, except for situations in which the global variables
-               could be converted into const types.  Otherwise, they are passed
-               by reference through the functions.
-
- Description:  Begin mods for file I/O removal
-
- Description:  Merged trans4m_freq_2_time, trans4m_time_2_freq, etc.
-
- Description:  Removing commented out sections of code.  This includes the
-               removal of unneeded functions init_lt_pred, reset_mc_info,
-
- Description: Copied from aac_decode_frame.c and renamed file,
-              Made many changes.
-
- Description: Prepare for code review
-
- Description: Update per review comments:
-              1) Add comment about leaveGetLoop
-              2) Remove inverseTNSCoef array
-              3) fix wnd_shape_this_bk to wnd_shape_prev_bk in F to T
-              4) Clean up comments
-              5) Change call to long_term_synthesis
-
- Description: Remove division for calculation of bitrate.
-
- Description: Remove update of LTP buffers if not LTP audio object type.
-
- Description: Add hasmask to call to right_ch_sfb_tools_ms
-
- Description:
- Modified to call ltp related routines on the left channel
- before intensity is called on the right channel.  The previous version
- was causing a problem when IS was used on the right channel and LTP
- on the left channel for the same scalefactor band.
-
- This fix required creating a new function, apply_ms_synt, deleting another
- function (right_ch_sfb_tools_noms.c), and modifying the calling order of
- the other functions.
-
- Description: Made changes per review comments.
-
- Description: Changed name of right_ch_sfb_tools_ms to pns_intensity_right
-
- Description: Added cast, since pVars->inputStream.usedBits is UInt, and
- pExt->remainderBits is Int.
-
- pExt->remainderBits =
-    (Int)(pVars->inputStream.usedBits & INBUF_BIT_MODULO_MASK);
-
- Description: Modified to pass a pointer to scratch memory into
- tns_setup_filter.c
-
- Description: Removed include of "s_TNSInfo.h"
-
- Description: Removed call to "tns_setup_filter" which has been eliminated
- by merging its functionality into "get_tns"
-
- Description:  Passing in a pointer to a q-format array, rather than
- the address of a single q-format, for the inverse filter case for
- apply_tns.
-
- Description:
- (1) Added #include of "e_ElementId.h"
-     Previously, this function was relying on another include file
-     to include "e_ElementId.h"
-
- (2) Updated the copyright header.
-
- Description:
- Per review comments, declared two temporary variables
-
-    pChLeftShare  = pChVars[LEFT]->pShareWfxpCoef;
-    pChRightShare = pChVars[RIGHT]->pShareWfxpCoef;
-
- Description:
-    long_term_synthesis should have been invoked with max_sfb
-    as the 2nd parameter, rather than pFrameInfo->sfb_per_win[0].
-
-    Old
-                long_term_synthesis(

-                    pChVars[ch]->pShareWfxpCoef->max_sfb ...
-
-    This problem caused long_term_synthesis to read memory which
-    was not initialized in get_ics_info.c
-
- Description:
- (1) Utilize scratch memory for the scratch Prog_Config.
-
- Description: (1) Modified to decode ID_END syntactic element after header
-
- Description:
- (1) Reconfigured LTP buffer as a circular buffer.  This saves
-     2048 Int16->Int16 copies per frame.
-
- Description: Updated so ltp buffers are not used as a wasteful
- intermediate buffer for LC streams.  Data is transferred directly
- from the filterbank to the output stream.
-
- Description: Decode ADIF header if frame count is zero.
-              The AudioSpecificConfig is decoded by a separate API.
-
- Description: Added comments explaining how the ltp_buffer_state
- variable is updated.
-
-
- Description: Modified code to take advantage of new trans4m_freq_2_time_fxp,
- which writes the output directly into a 16-bit output buffer.  This
- improvement allows faster operation by reducing the amount of memory
- transfers.  Speed can be further improved on most platforms via use of a
- DMA transfer in the function write_output.c
-
- Description: perChan[] is an array of structures in tDec_Int_File. Made
-              corresponding changes.
-
- Description: Included changes in interface for q_normalize() and
-              trans4m_freq_2_time_fxp.
-
- Description: Included changes in interface for long_term_prediction.
-
- Description: Added support for DSE (Data Streaming Channel). Added
-              function get_dse() and included file get_dse.h
-
- Description: Added support for the ill-case when a raw data block contains
-              only a terminator <ID_END>. This is illegal but is added
-              for convinience
-
- Description: Added support for empty audio frames, such the one containing
-              only DSE or FILL elements. A trap was added to stop processing
-              when no audio information was sent.
-
- Description: Added support for adts format files. Added saturation to
-              floating point version of aac+ decoding

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    pExt = pointer to the external interface structure. See the file
-           PVMP4AudioDecoder_API.h for a description of each field.
-           Data type of pointer to a tPVMP4AudioDecoderExternal
-           structure.
-
-    pMem = void pointer to hide the internal implementation of the library
-           It is cast back to a tDec_Int_File structure. This structure
-           contains information that needs to persist between calls to
-           this function, or is too big to be placed on the stack, even
-           though the data is only needed during execution of this function
-           Data type void pointer, internally pointer to a tDec_Int_File
-           structure.
-
- Local Stores/Buffers/Pointers Needed: None
-           (The memory set aside in pMem performs this task)
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
-     status = 0                       if no error occurred
-              MP4AUDEC_NONRECOVERABLE if a non-recoverable error occurred
-              MP4AUDEC_RECOVERABLE    if a recoverable error occurred.
-              Presently a recoverable error does not exist, but this
-              was a requirement.
-
-
- Pointers and Buffers Modified:
-    pMem contents are modified.
-    pExt: (more detail in the file PVMP4AudioDecoder_API.h)
-    inputBufferUsedLength - number of array elements used up by the stream.
-    remainderBits - remaining bits in the next UInt32 buffer
-    samplingRate - sampling rate in samples per sec
-    bitRate - bit rate in bits per second, varies frame to frame.
-    encodedChannels - channels found on the file (informative)
-    frameLength - length of the frame
-
- Local Stores Modified: None.
-
- Global Stores Modified: None.

-     to include "e_ProgConfigConst.h"
-
- (2) Updated the copyright header.
-
- Description:
- (1) Modified to initialize pointers for shared memory techniques.
-
- Description: Since memory will be allocated continuously, it is initialized
-              in one spot
-
- Description: Added field aacPlusUpsamplingFactor (default == 1) to have a
-              common interface for all AAC variations
-
- Description: Added PVMP4AudioDecoderDisableAacPlus to disable sbr decoding

- Inputs:
-    pExt = pointer to the external application-program interface (API)
-           structure that a client program uses to communicate information
-           with this library. Among the items in this structure is a pointer
-           to the input and output buffers, data for handling the input buffer
-           and output information. Look in PVMP4AudioDecoder_API.h for all the
-           fields to this structure. Data type pointer to a

-
-   pMem =  pointer to allocated memory, of the size returned by the function
-           PVMP4AudioDecoderGetMemRequirements. This is a void pointer for
-           two reasons:
-           1) So the external program does not need all of the header files
-              for all of the fields in the structure tDec_Int_File
-           2) To hide data and the implementation of the program. Even knowing

- FUNCTION DESCRIPTION
-
-  This function is called when the same audio clip will be played again from
-  the begining. This situation happens when the "stop" button is pressed or
-  the "loop-mode" is selected on PVPlayer. Since it is the same audio clip to
-  be played again, the decoder does not need to reset the audioSpecificInfo.
-  However, the overlap-and-add buffer of the filterbank output needs to be
-  cleared, so that the decoder can re-start properly from the begining of
-  the audio. The frame number counter, pVars->bno, is set to 1 because the
-  audioSpecificInfo is decoded on pVars->bno==0

- REVISION HISTORY
-
- Who:                                         Date:
- Description:
-
-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    pExt = pointer to the external interface structure. See the file
-           PVMP4AudioDecoder_API.h for a description of each field.
-           Data type of pointer to a tPVMP4AudioDecoderExternal
-           structure.
-
-           pExt->pInputBuffer: pointer to input buffer containing input
-                               bitstream
-
-           pExt->inputBufferCurrentLength: number of bytes in the input buffer
-
-           pExt->inputBufferUsedLength: number of bytes already consumed in
-                                        input buffer
-
-           pExt->remainderBits: number of bits consumed in addition to
-                                pExt->inputBufferUsedLength
-
-    pMem = void pointer to hide the internal implementation of the library
-           It is cast back to a tDec_Int_File structure. This structure
-           contains information that needs to persist between calls to
-           this function, or is too big to be placed on the stack, even
-           though the data is only needed during execution of this function
-           Data type void pointer, internally pointer to a tDec_Int_File
-           structure.
-
- Local Stores/Buffers/Pointers Needed: None
-           (The memory set aside in pMem performs this task)
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
-     status = 0                       if no error occurred
-              MP4AUDEC_NONRECOVERABLE if a non-recoverable error occurred
-              MP4AUDEC_RECOVERABLE    if a recoverable error occurred.
-              Presently a recoverable error does not exist, but this
-              was a requirement.
-
-
- Pointers and Buffers Modified:
-    pMem contents are modified.
-    pExt: (more detail in the file PVMP4AudioDecoder_API.h)
-    inputBufferUsedLength - number of array elements used up by the stream.
-    remainderBits - remaining bits in the next UInt32 buffer
-    samplingRate - sampling rate in samples per sec
-    encodedChannels - channels found on the file (informative)
-    frameLength - length of the frame
-
- Local Stores Modified: None.
-
- Global Stores Modified: None.

- FUNCTION DESCRIPTION
-
- This module first scans every scalefactor band for the frame, insuring that
- at least one element in that scalefactor band is using all available bits.
- If not, the elements in the scalefactor band are shifted up to use all 31
- data bits.  The q-format is adjusted accordingly.
-
- This module then scans the q-formats for each scalefactor band.
- Upon finding the minimum q-format in the frame, the coefficients in each
- scalefactor band are normalized to the minimum q-format.
- The minimum q-format is then returned to the calling function, which is now
- the q-format for the entire frame.

- Pathname: LT_PRED_STATUS.h
-
-
-------------------------------------------------------------------------------
- REVISION HISTORY
-
- Description:
- (1) Merged in #defines from ltp_common.h, thereby eliminating that file.
-
- Description:
- (1) Modified to include the lines...
-
-    #ifdef __cplusplus
-    extern "C" {
-    #endif
-
-    #ifdef __cplusplus
-    }
-    #endif
-
- (2) Updated the copyright header.
-
- Description: Moved large ltp_buffer up to s_tDec_Int_Chan.h, since this
- move allowed for other elements in this structure to be shared with
- the fxpCoef array.
-
- Description: Decreased size of LTP buffers from 4096 to 3072.  The upper 1024
- elements in the LTP buffers were never touched in the code.  This saves
- 4 kilobytes in memory.
-
- Description: Decreased size of LTP buffers again from 3072 to 2048.  This
- time, I realized that 1024 elements were duplicated in the 32-bit array
- pVars->pChVars[]->time_quant.  Rather than copy this data EVERY frame
- from a 32-bit to a 16-bit LTP buffer, the data is accessed only

- Description: Modified to eliminate triple-nested structure, which wasted
- 2 KB of memory.
-
- Description:
- (1) Modified to include the lines...

-    #ifdef __cplusplus
-    extern "C" {
-    #endif
-
-    #ifdef __cplusplus

-    #endif
-
- (2) Updated the copyright header.
-
- Description:
- (1) Changed hard coded size of arrays from "8" to "TNS_MAX_WIN"
- (2) Moved elements from s_TNSinfo.h up to the level of TNS_frame_info
- (3) Added Bool "tns_data_present" for future use.
- (4) Moved lpc_coef up from s_TNSfilt.h (allowed for use of smaller array.)
-
- Description:
- (1) Removed the array "coef_res", which is now a local variable on the

- REVISION HISTORY
-
- Description: Added lpc, start, & size, so the data from
- tns_inv_subblock can be shared with tns_decode_subblock.
-
- Description: Removed lpc to save 2KB of memory (on 32-bit machines.)
- This change requires tns_decode_coef.c to perform calculations in place.
-
- Description: Removed start & size.  start_band and stop_band can simply
- take on a new meaning after this function.  (coef index, rather than
- scalefactor band index.)
-
- Description: Had to add "start_coef" and "stop_coef" in order to preserve
- values "start_band" and "stop_band."  This required a change to
- tns_setup_filter.c also.
-
- Description: Had to add element "q_lpc" to store the q-format of the lpc
- coefficients passed via "coef."
-
- Description: Moved lpc_coef array up to the s_TNS_frame_info.h structure.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Implemented 24-bit fixed point version
-               Optimized C code
-
- Description:
-            - Added OVERFLOW_SHIFT_DOWN to avoid overflow.
-            - Increased precision by using the Q format of the LPC coefficient.
-            - Modified interface to add LPC Q format and scratch memory
-              for the state variables.
-            - Added pv_memset to clear state filter
-            - Updated format for comments (to PV standard)
-            - Updated copyright notice
-
- Description:
-            - Changed multiplication scheme to increase precision. This
-              works better than older version.
-
- Description:
-            - Include log2(order) as a scaling down parameter.
-
- Description:
-            Modified to reflect code review comments
-                - misspelled words, extra comments and explicit requirements
-
- Description:
-            deleted comment about fix Q format (L 107)
-
- Description:  Implemented a more efficient version, which eliminated the use
- of "scratch memory" via introducing a pointer that references the actual
- output.
-
- Description: Removed the parameter "scratch_Int32_buffer" as this space
- in memory is no longer needed by this function.
-
- Description: Removed references to "scratch_Int32_buffer" in the Inputs
- section.
-
- Description:
-    Modified casting to ensure proper operations for different platforms
-
- Description:
-    Per code review comment:
-    Eliminated casting to UInt and Int in b_low and b_high, they are
-    redundant and may add unncessary extra cycles in some platforms
-
- Description: Updated the SW template to include the full pathname to the
- source file and a slightly modified copyright header.
-
- Description: Changed the order of the unsigned * signed multiply so the
- casting to Int32 is performed on the unsigned operand.
-
- Description:
-    Modified 32 by 16 bit multiplications to avoid unnecessary moves to
-    registers. Also split the code (based on flag direction) to simplify
-    pointer's updates
-
- Description:
-

- FUNCTION DESCRIPTION
-
-    A block of spectral data (Int32 spec[]) of length (const Int spec_length)
-    is processed by a simple all-pole filter defined by
-    LPC coefficients passed via (const Int lpc[])
-
-    TNS filter equation
-        y(n) =  x(n) - lpc(2)*y(n-1) - ... - lpc(order+1)*y(n-order)
-
-    The filter calculation is performed in place, i.e. the output is passed
-    back to the calling function via (Int32 spec[])
-
-    The filter's order is defined by the variable (const Int order)
-    The direction of the filter's application is defined by (const Int inc)
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    This function should match the functionality of the ISO code.
-    The implementation does support filter orders bigger or equal to 1.
-    The size of the spectral coeffcients has to be bigger or equal than 1.

- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Implemented in 16-bit Fixed Point
-
- Description:  Implemented in 24-bit Fixed Point
-
- Description:  Modified to return the calculated LPC coefficients "in place"
- This saves memory, cycles, etc. because it saves a large temporary
- array being declared on the stack in another function (tns_setup_filter)
-
- Description:  Modified to return the q-format of the lpc coefficients.
-
- Description:  Modified for more reliable overflow protection.  tns_decode_coef
- no longer relies on "reasonable" outputs.  This code should handle all
- possible inputs.
-
- Description:  Modified per review comments.
-
- Description:  Added check condition to avoid numbers with a Q bigger than
-        15 from being passed, otherwise in a 16-bit number the sign is lost.
-
- Description:  Modified to utilize scratch memory techniques, thereby
- eliminating two arrays of size TNS_MAX_ORDER, which were previously declared
- on the stack.
-
- Description: Updated the SW template to include the full pathname to the
- source file and a slightly modified copyright header.
-
- Description:
- (1) Changed the order of the unsigned * signed multiply so the
-     casting to Int32 is performed on the unsigned operand.
-
- (2) Removed some unnecessary casting.
- (3) Fixed a problem where a 16-bit value was casted to 32-bits AFTER
-     a shift.  It should have been cast to 32-bits BEFORE the shifting.
-
-
- Description:  modified precision of coefficients

- FUNCTION DESCRIPTION
-
-    A block of spectral data (Int32 coef[]) of length (const Int num_coef)
-    is processed by a simple all-zero filter defined by
-    LPC coefficients passed via (const Int lpc[])
-
-    TNS filter equation
-        y(n) =  x(n) + lpc(2)*x(n-1) + ... + lpc(order+1)*x(n-order)
-
-    The filter calculation is performed in place, i.e. the output is passed
-    back to the calling function via (Int32 coef[])
-
-    In order to avoid overflow, the filter input (Int32 coef[]) must utilize
-    only the lower 16-bits.  The upper 16-bits must be available.
-
-    The filter's order is defined by the variable (const Int order)
-
-    The direction of the filter's application is defined by
-    (const Int direction)
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    [Int32 coef] must store no more than 16 bits of data.
-
-    This is required to utilize methods that do not change the q-format of
-    the input data [Int32 coef], and to make use of a fast
-    16 x 16 bit multiply.
-
-    This function should not be called for order <= 0.
-
-    This function must not be called with lpc_qformat < 5

- REVISION HISTORY
-
- Description:
-    changed to decrement loop
-    change wnd_shape from structure to passing parameters
-    modified window tables from UInt to UInt16 to assure proper operation
-    without dubious typecast
-    changed logic to hit most common states first.
-    modified Time_data from Int to Int32 to hold
-    possible overflow before saturation process.
-
- Description:
-    Increase processing on some loop by using more pointers
-    changed interface to avoid passing a pointer for wnd_shape_prev_bk, this
-    element is not change in this function because of this function use
-    in the LTP module
-
- Description:
-    Added rounding to multiplication
-
- Description:
-    Update input description and eliminate unneeded comments
-
- Description:
-    LONG_START_WINDOW was using SHORT_WINDOW instead of
-    HALF_SHORT_WINDOW, causing a for loop to exceed its count
-
- Description:
-    Modified structure of code so exp is not tested before it
-    is initialized.  Also, new structure avoids double-testing
-    of exp_freq = ALL_ZEROS_BUFFER.
-
- Description:
-    The result of a shift is undefined if the right operand is greater than
-    or equal to the number of bits in the left expression's type
-    To avoid undefined shift by 32, a check of the shift has been
-    added, so the function proceeds only when the exponent is less
-    than 32. By design the shift up is related to the global gain,
-    and controlled by the encoder, so saturation is not allowed.
-    In both short and long window, processing is skip if an all zero
-    input buffer or excessive down shift is detected.
-
- Description:
-    Changes according to code review comments. Also, modified if-else
-    structure so the imdct_fxp is not called with an all zero input buffer
-
- Description:
-    Replaced function buffer_normalization by buffer_adaptation, to ease
-    use of 16 bits. Function buffer_normalization becomes  obsolete.
-
- Description:
-    Modified call to imdct_fxp to reflect extended precision use. Added
-    routine buffer_adaptation to extract 16 MSB and keep highest.
-    precision. Modify casting to ensure proper operations for different
-    platforms
-
- Description:
-    Eliminate double access to memory by loading data directly to the
-    time array. Also reduced cycle count and added precision by combining
-    downshifting in only one operation. Added adaptive rounding factor.
-    Change exponent threshold when operations are waived. It is use to be 32
-    but by combining downshifting, this new threshold is now 16. This may
-    avoid unneeded calculations for extremely small numbers.
-
- Description:
-    Per review comments:
-        - Added comments to clarify buffer_adaptation function
-        - Deleted  reference to include file "buffer_normalization.h"
-        - Modified IF-ELSE so long_windows case is considered first
-        - Eliminated extra IF when computing the rounding, so when exp ==0
-          less cycles are used shifting than in an extra if-else
-        - Corrected negative shift when computing rounding factor
-        - Added condition when exp > 16 (for long windows)
-
- Description:
-    Modified IF-ELSE structure so now ALL_ZEROS_BUFFER condition is share
-    with exp > 16 condition. This avoid code duplication for both cases.
-
- Description:
-        - Modified function interface to add output_buffer
-        - Eliminated the 32 bit version of the current output, calculations
-          are placed directly in output_buffer. In this way the buffer
-          Time_data needs only to be 1024 Int32, instead of 2048 (per channel).
-          Also, added the limit macro inside the function (this reduces access
-          to memory).
-        - Updated Pseudo - Code
-
- Description:
-    Per review comments:
-          Corrected line sizes and mispelling,  added comments and swap
-          order or switch statement for ONLY_LONG_SEQUENCE.
-
- Description:
-    Eliminated adaptive rounding due to potential saturation.
-
- Description:
-    Eliminated use of buffer adaptation by shifting this functionality inside
-    the imdct_fxp() routine. Also modified the call to imdct_fxp to accomodate
-    new function interface.
-    Modified macro limit() to save cycles when testing the most common case:
-    no saturation.
-
- Description:
-    Changed new function interface for imdct_fxp().
-
- Description:
-    Replaced for-loop with memset and memcopy.

- FUNCTION DESCRIPTION
-
-The time/frequency representation of the signal is mapped onto the time
-domain by feeding it into the filterbank module. This module consists of
-an inverse modified discrete cosine transform (IMDCT), and a window and an
-overlap-add function. In order to adapt the time/frequency resolution of the
-filterbank to the characteristics of the input signal, a block switching tool
-is also adopted. N represents the window length, where N is a function of the
-window_sequence. For each channel, the N/2 time-frequency values are
-transformed into the N time domain values via the IMDCT. After applying the
-window function, for each channel, the first half of the sequence is added to
-the second half of the previous block windowed sequence to reconstruct the
-output samples for each channel outi,n.
-
-The adaptation of the time-frequency resolution of the filterbank to the
-characteristics of the input signal is done by shifting between transforms
-whose input lengths are either 2048 or 256 samples. By enabling the block
-switching tool, the following transitions are meaningful:
-
-from ONLY_LONG_SEQUENCE to   { LONG_START_SEQUENCE
-                               ONLY_LONG_SEQUENCE
-
-from LONG_START_SEQUENCE to  { LONG_STOP_SEQUENCE
-                               EIGHT_SHORT_SEQUENCE
-
-from LONG_STOP_SEQUENCE to   { LONG_START_SEQUENCE
-                               ONLY_LONG_SEQUENCE
-
-from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE
-                               EIGHT_SHORT_SEQUENCE
-
-Window shape decisions are made by the encoder on a frame-by-frame-basis.
-The window selected is applicable to the second half of the window function
-only, since the first half is constrained to use the appropriate window
-shape from the preceding frame.
-The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are
-the last 1024 values of the previous window_sequence concatenated with 1024
-values of the current block. The formula below shows this fact:
-
-                     |  x(i-1)(n+1024)      for    0 < n < 1024
-            x'(i)(n) {
-                     |  x(i)(n)             for 1024 < n < 2048
-
-
-Buffer Time_data data from previous Frequency to Time conversion, used
-for overlap and add
-
-Once the window shape is selected, the window_shape syntax element is
-initialized. Together with the chosen window_sequence all information needed
-for windowing exist.
-With the window halves described below all window_sequences can be assembled.
-For window_shape == 1, the window coefficients are given by the Kaiser -
-Bessel derived (KBD) window.
-Otherwise, for window_shape == 0, a sine window is employed.
-
-The window length N can be 2048 or 256 for the KBD and the sine window.
-All four window_sequences explained below have a total length of 2048
-samples.
-For all kinds of window_sequences the window_shape of the left half of
-the first transform window is determined by the window shape of the previous
-block.
-
-In the case of EIGHT_SHORT_SEQUENCE the processing is done in-place and
-in descendent order to avoid using extra memory.
-The ordering is as follows:
-
-                                            Pn: Previous data for window n
-                                            Cn:  Current data for window n

- REVISION HISTORY
-
- Description:
-        Modified normalization, so it now happen per window basis, eliminated
-        shifts left or rigth to accomodate TNS inverse filtering. The output
-        is 32 bits but only the lowest 16 are being used.
-        Modified fuction interface
-
- Description: Modified variable names with leading "p" for pointers
-
- Description:
-        Modified call to mdct_fxp to reflect extended precision use. Added routine
-        buffer_adaptation to extract 16 MSB and keep highest precision.
-        Modify casting to ensure proper operations for different platforms
-
- Description:
-        Added comments according to code review
-
- Description:
-        Removed include file "buffer_normalization.h"
-
- Description:
-        Eliminated buffer_adaptation() and embedded its functionality in other
-        functions. Commented out the short window section given that this is
-        not supported by the standards
-
- Description:
-        Added shift down operation for case when the window was equal to one.
-        This was not needed previuosly because buffer_adaptation() was doing
-        it.
-
- Description: Created local version of vectors Long_Window_fxp and
-              Short_Window_fxp. This solve linking problem when using the
-              /ropi option (Read-only position independent) for some
-              compilers.

- FUNCTION DESCRIPTION
-
-The time/frequency representation of the signal is mapped onto the frequency
-domain by feeding it into the filterbank module. This module consists of
-a modified discrete cosine transform (MDCT), (windowing and DCT).
-In order to adapt the time/frequency resolution of the filterbank to the
- characteristics of the input signal, a block switching tool is also
-adopted. N represents the window length, where N is a function of the
-window_sequence. For each channel, the N time values are transformed into the
-N/2 frequency domain values via the MDCT.
-
-The adaptation of the time-frequency resolution of the filterbank to the
-characteristics of the input signal is done by shifting between transforms
-whose input lengths are either 2048 or 256 samples. By enabling the block
-switching tool, the following transitions are meaningful:
-
-from ONLY_LONG_SEQUENCE to   { LONG_START_SEQUENCE
-                               ONLY_LONG_SEQUENCE
-
-from LONG_START_SEQUENCE to  { LONG_STOP_SEQUENCE
-                               EIGHT_SHORT_SEQUENCE
-
-from LONG_STOP_SEQUENCE to   { LONG_START_SEQUENCE
-                               ONLY_LONG_SEQUENCE
-
-from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE
-                               EIGHT_SHORT_SEQUENCE
-
-Window shape decisions are made by the encoder on a frame-by-frame-basis.
-The window selected is applicable to the second half of the window function
-only, since the first half is constrained to use the appropriate window
-shape from the preceding frame.
-The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are
-the last 1024 values of the previous window_sequence concatenated with 1024
-values of the current block. The formula below shows this fact:
-
-                     |  x(i-1)(n+1024)      for    0 < n < 1024
-            x'(i)(n) {
-                     |  x(i)(n)             for 1024 < n < 2048
-
-
-
-Once the window shape is selected, the window_shape syntax element is
-initialized. Together with the chosen window_sequence all information needed
-for windowing exist.
-With the window halves described below all window_sequences can be assembled.
-For window_shape == 1, the window coefficients are given by the Kaiser -
-Bessel derived (KBD) window.
-Otherwise, for window_shape == 0, a sine window is employed.
-
-The window length N can be 2048 or 256 for the KBD and the sine window.
-All four window_sequences explained below have a total length of 2048
-samples.
-For all kinds of window_sequences the window_shape of the left half of
-the first transform window is determined by the window shape of the previous
-block.
-------------------------------------------------------------------------------
- REQUIREMENTS
-
-    This module shall implement a scheme to switch between window types and
-    in turn perform time to frequency transformations

-------------------------------------------------------------------------------
- REVISION HISTORY
-
- Description:  Modified from original shareware code
-
- Description:  Eliminated 3 divisions and 1 multiplication through a table
- look-up method for calculating 1/mod and constant allocation of 1/mod^3
- and 1/mod^2.
- Eliminated 3 additions through simple optimizations in the code.
- Changed if/else  statement to a switch/case utilizing fall-through.
-
- Description:   Made changes per review comments.  Main improvements were
- in change of switch/case to if statement, and use of temporary variable
- to hold value of *pQuantSpec.
-
- Description: (1) Typecast codeword_indx to Int32 before multiplication, this
-              assures the shift operation happens on a 32-bit product on
-              TI-C55x processor.
-              (2) define temp_spec as Int32 to avoid overflow
-
- Description: Modified per review comments
-              (1) remove the two typecastings of codeword_indx when
-                  pHuffCodebook->dim == DIMENSION_4
-              (2) temp_spec is Int because the result never exceeds 16 bits
-
- Description: Break up and combine unpack index with sign bit reading and for
-              special escape code. Parent function must know which one of the
-              3 functions should be called.
-
- Description: Put back if-statement to get the max.
-
- Description: When searching for the max, there was some instances where the
-              max was compared against a negative number, so the max was never
-              updated (defaulted to 0), leading to block processing in other
-              magnitude sensitive stages.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-          Int  quant_spec[]  = Array for storage of the quantized
-                               spectral coefficients.  Length is either 2 or 4.
-                               See Ref #1, Page 76 for a complete description.
-
-          Int  codeword_indx = The index into the Huffman table.
-                               Range is [1-288]
-
-    const Hcb *pHuffCodebook = Pointer to HuffmanCodebook information.
-
-          BITS  *pInputStream = Pointer to the bitstream buffer.
-          Int *max           = Pointer to maximum coefficient value.
-
- Local Stores/Buffers/Pointers Needed:
-    const UInt div_mod[18]   = An array with the values for 1/mod
-                               stored in Q-formats 13.
-
- Global Stores/Buffers/Pointers Needed:
-    None
-
- Outputs:
-    None
-
- Pointers and Buffers Modified:
-    Int quant_spec[] = Output (the quantized and signed spectral coefficients)
-                       returned via this pointer.
-
- Local Stores Modified:
-    None
-
- Global Stores Modified:
-    None

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function decodes quantized spectral coefficients and decode their signs
- from the input bitstream. Quantized spectral coefficients are transmitted as
- four-tuples or 2-tuples, and this information is conveyed to the function via
- the variable HuffCodebook->dim.
-
- See Reference #1 for a complete description
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function shall correctly calculate pQuantSpec[], given the inputs
-
- codeword_indx     = {1-288};
- HuffCodebook->off = {0, 1, 4};
- HuffCodebook->mod = {3, 8, 9, 13, 17};
-
- mod =   LAV + 1 if unsigned codebook
- mod = 2*LAV + 1 if   signed codebook
-
- Range of values for LAV is {2,7,12,16} if unsigned
-                            {1,4}       if   signed
-
- Additionally,
-     LAV <= 2 if dim == 4
-
- This restricts mod ==  3                if dim == 4
-            and mod == {3, 8, 9, 13, 17} if dim == 2
-
- This function will NOT function correctly if fed values that do not
- meet the requirements as stated above.
-
- This limitation on the range of values was determined by analysis
- of Reference #1 (see below.)
