- 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.

- * 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: Reduce the accuracy of w_256rx4 and w_512rx2 to Q10 format.
- Try to to pack sin and cos into one 32-bit number to reduce the
- memory access, but doesn't help in speed, so commented out for now.
-
- Description:
- (1) Reduced precision of w_64rx4 from Q15 to Q12.
- (2) Increased precision of w_512rx2 from Q10 to Q13, Both changes
- increase overall decoder precision
-
- Description:
- (1) per code review comment, added description for table generation
- (2) modified definition of w_64rx4 from Int to Int16

- 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.

- 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.
-
-------------------------------------------------------------------------------

-
- fwd_long_complex_rot() should execute a pre-rotation by
- exp(-j(2pi/N)(k+1/8)), digit reverse ordering and 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

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs: random_array[] = Array for storage of the power-scaled
- random values of length "band_length"
- Int32
-
- band_length = Length of random_array[]
- const Int
-
- pSeed = seed for random number generator
- Int32*
-
- power_scale = scale factor for this particular band
- const Int
-
-
- Local Stores/Buffers/Pointers Needed:
- None
-
- Global Stores/Buffers/Pointers Needed:
- None
-
- Outputs: Function returns the q-format the random vector is stored in.
-
- Pointers and Buffers Modified:
- random_array[] = filled with random numbers scaled
- to the correct power as defined by the input value power_scale.
-
- Local Stores Modified:
- None
-
- Global Stores Modified:
- None
-
-------------------------------------------------------------------------------
- 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.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- pVars = pointer to the structure that contains the current state
- of this instance of the library, of data type pointer to

- pScratchPCE = pointer to a ProgConfig structure used as scratch in the
- the function get_prog_config. of data type pointer to
- ProgConfig
-
- Local Stores/Buffers/Pointers Needed: None
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
- The function returns 0 if no error occurred, non-zero otherwise.
-
- Pointers and Buffers Modified:
- pVars->adif_header contents are updated with the some of the ADIF header
- contents
- pVars->tempProgConfig contents are overwritten with last PCE found,
- which is most likely the first one found.
- pVars->prog_config contents are updated with the first PCE found.
- pVars->inputStream contents are modify in such a way that the
- stream is moved further along in the buffer.
- pVars->SFBWidth128 contents may be updated.
- pVars->winSeqInfo contents may be updated.
- pScratchPCE contents may be updated.
-
- Local Stores Modified: None
-
- Global Stores Modified: None
-
-------------------------------------------------------------------------------
- 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.

- 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.
-
- CRC_absent sampling_rate_idx

- 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.

- Description: Modified from original shareware code
-
- Description: Modified to pass variables by reference to eliminate use
- of global variables.
-
- Description: Move functionality from get_adif_header for when to change
- the current program configuration, add a temporary config
- to read into, clean up code, change function prototype.
-
- Description: Clean up
-
- Description: Update per review comments
-
- Description: Fix double 'could'
-
- Description: change enter_mc_info to set_mc_info
-
- Description: update comments
-
- 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.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- pVars = pointer to the structure that holds all information for
- this instance of the library. pVars->prog_config is directly
- used, and pVars->mc_info, pVars->prog_config, pVars->winmap,
- pVars->SFBWidth128 are needed indirectly for calling
- set_mc_info. Data type pointer to tDec_Int_File structure.
-
- pScratchPCE = pointer to a temporary ProgConfig structure to be used
- to read in the program configuration element.
-
- Local Stores/Buffers/Pointers Needed: None
-
- Global Stores/Buffers/Pointers Needed: None
-
- Outputs:
- status = zero if no error was found, non-zero otherwise.
-
- Pointers and Buffers Modified:
- pVars->prog_config contents are updated with the PCE read in.
- pVars->mc_info contents are updated with channel information.
- pVars->winmap contents are updated with window information.
- pVars->SFBWidth128 contents are updated with scale factor band width data.
-
- Local Stores Modified: None
-
- Global Stores Modified: None
-
-------------------------------------------------------------------------------
- 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.

- Pathname: get_pulse_data.c
-
-------------------------------------------------------------------------------
- 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:
- Description:
-------------------------------------------------------------------------------
- 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.
-
- Local Stores Modified:
-
- Global Stores Modified:
-
-
-------------------------------------------------------------------------------
- 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.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- pInputStream = pointer to structure that holds input bitstream
- information. Type BITS
-
- group[] = array that holds the index of the first window in each
- group. Type Int
-
- Local Stores/Buffers/Pointers Needed:

-
-------------------------------------------------------------------------------
- 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.
- 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.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- pFrameInfo = pointer to structure that holds information for current
- frame, Type FrameInfo
-
- pInputStream= pointer to structure that holds input stream information
- Type BITS
-
- pGroup = pointer to array that holds the stop window index for
- each group in current frame, Type Int
-
- max_sfb = number of active sfbs for each window, Type Int
-
- mask[] = array that holds the MS_mask information
- Type Int
-
- Local Stores/Buffers/Pointers Needed:
- None
-
- Global Stores/Buffers/Pointers Needed:
- None
-
- 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
-
- Local Stores Modified:
- 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

- REVISION HISTORY
-
- Description: Modifiy per review comments
- (1) delete the following comments:
- The LAV field has been deleted, since it is never used.
-
- Description: Remove old structure of huffman table and add new table structure.
-
- Description: Modified structure to avoid assigning addresses to constant
- tables. This solve linking problem when using the
- /ropi option (Read-only position independent) for some
- compilers
- - Eliminated references to contant vector addresses in
- hcbbook_binary

-/* New look-up table for huffman decoding
- 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
-
- 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"
- (4) eliminated multiple returns, use return valid
-
- 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

- Pathname: huffspec_fxp.c
- Funtions:
- huffspec_fxp
-
-------------------------------------------------------------------------------
- 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.
-
-
- where X(k) is the input with N frequency lines
-
- X(k) ----------------------------
- |
- |
- Pre-rotation by exp(j(2pi/N)(k+1/8))
- |
- |
- N/4- point IFFT
- |
- |
- Post-rotation by exp(j(2pi/N)(n+1/8))
- |
- |
- ------------- x(n) In the time domain
-
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This function should provide a fixed point IMDCT with an average
- quantization error less than 1 % (variance and mean).

- 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;
-
- Description:
-------------------------------------------------------------------------------
- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-
- scalefactor = Multiplier used to scale the data extracted from the left
- channel for use on the right.
- [const Int]
-
- coef_per_win = Number of coefficients per window.
- (128 for short, 1024 for long)
- [const Int]
-
- sfb_per_win = Number of scalefactor bands per window. This should be
- a number divisible by four.
- [const Int]
-
- wins_in_group = The number of windows in the group being decoded.
- This number falls within the range 1-8.
- [const Int]
-
- band_length = The length of the scalefactor band being decoded.
- This value is divisible by 4.
- [const Int]
-
- codebook = Value that denotes which Huffman codebook was used for
- the encoding of this grouped scalefactor band.
- [const Int]
-
- ms_used = Flag that denotes whether M/S is active for this band.
- [const Bool]
-
- q_formatLeft = The Q-format for the left channel's fixed-point spectral
- coefficients, on a per-scalefactor band, non-grouped basis.
- [const Int *, length MAXBANDS]
-
- q_formatRight = The Q-format for the right channel's fixed-point spectral
- coefficients, on a per-scalefactor band, non-grouped basis.

- for the right channel.
- [Int32 *, length 1024]
-
- Local Stores/Buffers/Pointers Needed:
- intensity_factor = Table which stores the values of
- 0.5^(0), 0.5^(1/4), 0.5^(2/4) and 0.5^(3/4)
- [UInt, length 4]
-
- Global Stores/Buffers/Pointers Needed:
- None
-
- Outputs:
- None
-
- Pointers and Buffers Modified:
- coefRight[] Contains the new spectral information
-
- q_formatRight[] Q-format may be updated with changed fixed-point
- data in coefRight.
-
- Local Stores Modified:
- None
-
- Global Stores Modified:
- None
-
-------------------------------------------------------------------------------
- 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]

- 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
-

- 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
- predicted time domain signals.
-
- buffer_index = index into buffer where the first sample of data from
- the frame (t-2) (two frames ago) resides. (Int)
-
- frame_length = length of one frame, type of Int.
-
- Local Stores/Buffers/Pointers Needed:
- None
-
- Global Stores/Buffers/Pointers Needed:
- None
-
- Outputs:
- Amount of shifting needed to grab the top 16 MSB from teh predicted buffer
-
- Pointers and Buffers Modified:
- predicted_samples contents are the newly calculated predicted time
- domain signals
-
- Local Stores Modified:
- None
-
- Global Stores Modified:
- None
-
-------------------------------------------------------------------------------
- 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

-
- 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.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
- data_quant = Input vector, with quantized Q15 spectral lines:
- type Int32
-
- Q_FFTarray = Scratch memory used for in-place IFFT calculation,
- min size required 1024, type Int32
-
- n = Length of input vector "data_quant". Currently 256 or 2048.
- type const Int
-
- Local Stores/Buffers/Pointers Needed:
- None
-
- Global Stores/Buffers/Pointers Needed:
- None
-
- Outputs:
- shift = shift factor to reflect scaling introduced by FFT and mdct_fxp,
-
- Pointers and Buffers Modified:
- calculation are done in-place and returned in "data_quant"
-
- Local Stores Modified:

-------------------------------------------------------------------------------
- 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.
-
- Description: per code review comments, eliminated unnecessary headers

- 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

- spectral coef's for the LEFT channel.
-
- Int q_format[] = Q-format for the information
- pointed to by spectral_coef.

- Outputs:
-
- Pointers and Buffers Modified:
- Int32 spectral_coef[] = Contains the new spectral information

- Global Stores Modified:
-
-------------------------------------------------------------------------------
- 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

- 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: 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]->wnd,
- pFrameInfo->sfb_per_win[0] ...
-
- Correction
- long_term_synthesis(
- pChVars[ch]->wnd,
- 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
-
- 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.
-
- 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.
-
-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- Decodes one frame of an MPEG-2/MPEG-4 encoded audio bitstream.

- REVISION HISTORY
-
- Description: Copied from aac_decode_frame
-
- Description: Clean up.
-
- Description: Update per review comments
-
- Description: Add frame_length, fix mistake in pseudo-code.
- Change frame_length to frameLength, to matcht the API,
- look more professional, etc.
-
- Description:
- (1) Added #include of "e_ProgConfigConst.h"
- Previously, this function was relying on another include file
- 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

- tPVMP4AudioDecoderExternal structure.
-
- 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

- 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

- 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.

-------------------------------------------------------------------------------
- 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
- when it is needed. This saves both MIPS and memory.

-
- Description: Removed lpc to save 2KB of memory (on 32-bit machines.)

-
- 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)

- 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

- 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
-

- 128 freq.

- 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.)

- REVISION HISTORY
-
- Description:
- changed table content definition from UInt to UInt16.
-
- Description:
- changed Long_Window_fxp and Short _Window_fxp tables definition, from
- "const UInt16 *" to "const UInt16 * const" to avoid global variable
- definition.
-
- Description:
- Improved rounding on table elements.
-
- Description: Eliminated structure to avoid assigning addresses to constant
- tables. This solve linking problem when using the
- /ropi option (Read-only position independent) for some
- compilers
- - Eliminated Long_Window_fxp and Short_Window_fxp as global
- contants vectors

- MODULE DESCRIPTION
-
- Window tables
-
- For a sine table with N points:
-
- w_left = sin(pi/N (n + 1/2)) for 0 =< n < N/2
-
- w_rigth = sin(pi/N (n + 1/2)) for N/2 =< n < N
-
-
- For Kaiser-Bessel derived (KBD)
-
- n N/2
- w_left = sqrt(( SUM W(p,a) )/( SUM W(p,a) ) for 0 =< n < N/2
- p=0 p=0
-
-
- N-n-1 N/2
- w_rigth = sqrt(( SUM W(p,a) )/( SUM W(p,a) ) for N/2 =< n < N
- p=0 p=0
-
-
- W(p,a) see ISO 14496-3, pag 113
-
-------------------------------------------------------------------------------
- REQUIREMENTS
-
- This module shall implement the fix point verwion of the windowing tables
