-A general purpose lookup utility that defines a mapping between X and Y as a
-continuous set of line segments with shared (x, y) end-points.
-The (x, y) points must be added in order, monotonically increasing in both x and y;
-a log warning is emitted if this does not happen (See general usage notes below).
-
-A limited history of (x, y) points is kept for space reasons (See general usage notes).
-
-In AudioFlinger, we use the LinearMap to associate track frames to
-sink frames.  When we want to obtain a client track timestamp, we first
-get a timestamp from the sink.  The sink timestamp's position (mPosition)
-corresponds to the sink frames written. We use LinearMap to figure out which track frame
-the sink frame corresponds to. This allows us to substitute a track frame for the
-the sink frame (keeping the mTime identical) and return that timestamp back to the client.
-
-The method findX() can be used to retrieve an x value from a given y value and is
-used for timestamps, similarly for findY() which is provided for completeness.
-
-We update the (track frame, sink frame) points in the LinearMap each time we write data
-to the sink by the AudioFlinger PlaybackThread (MixerThread).
-
-
-AudioFlinger Timestamp Notes:
-
-1) Example: Obtaining a track timestamp during playback.  In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-(track start)
-0              50000  (track starts here, the sink may already be running)
-1000           51000
-2000           52000
-
-When we request a track timestamp, we call the sink getTimestamp() and get for example
-mPosition = 51020.  Using the LinearMap, we find we have played to track frame 1020.
-We substitute the sink mPosition of 51020 with the track position 1020,
-and return that timestamp to the app.
-
-2) Example: Obtaining a track timestamp duing pause. In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-... (some time has gone by)
-15000          30000
-16000          31000
-17000          32000
-(pause here)
-(suppose we call sink getTimestamp() here and get sink mPosition = 31100; that means
-        we have played to track frame 16100.  The track timestamp mPosition will
-        continue to advance until the sink timestamp returns a value of mPosition
-        greater than 32000, corresponding to track frame 17000 when the pause was called).
-17000          33000
-17000          34000
-...
-
-3) If the track underruns, it appears as if a pause was called on that track.
-
-4) If there is an underrun in the HAL layer, then it may be possible that
-the sink getTimestamp() will return a value greater than the number of frames written
-(it should always be less). This should be rare, if not impossible by some
-HAL implementations of the sink getTimestamp. In that case, timing is lost
-and we will return the most recent track frame written.
-
-5) When called with no points in the map, findX() returns the start value (default 0).
-This is consistent with starting after a stop() or flush().
-
-6) Resuming after Track standby will be similar to coming out of pause, as the HAL ensures
-framesWritten() and getTimestamp() are contiguous for non-offloaded/direct tracks.
-
-7) LinearMap works for different speeds and sample rates as it uses
-linear interpolation. Since AudioFlinger only updates speed and sample rate
-exactly at the sample points pushed into the LinearMap, the returned values
-from findX() and findY() are accurate regardless of how many speed or sample
-rate changes are made, so long as the coordinate looked up is within the
-sample history.
-
-General usage notes:
-
-1) In order for the LinearMap to work reliably, you cannot look backwards more
-than the size of its circular buffer history, set upon creation (typically 16).
-If you look back further, the position is extrapolated either from a passed in
-extrapolation parameter or from the oldest line segment.
-
-2) Points must monotonically increase in x and y. The increment between adjacent
-points cannot be greater than signed 32 bits. Wrap in the x, y coordinates are supported,
-since we use differences in our computation.
-
-3) If the frame data is discontinuous (due to stop or flush) call reset() to clear
-the sample counter.
-
-4) If (x, y) are not strictly monotonic increasing, i.e. (x2 > x1) and (y2 > y1),
-then one or both of the inverses y = f(x) or x = g(y) may have multiple solutions.
-In that case, the most recent solution is returned by findX() or findY().  We
-do not warn if (x2 == x1) or (y2 == y1), but we do logcat warn if (x2 < x1) or
-(y2 < y1).
-
-5) Due to rounding it is possible x != findX(findY(x)) or y != findY(findX(y))
-even when the inverse exists. Nevertheless, the values should be close.

-/**
- * The Visualizer class enables application to retrieve part of the currently playing audio for
- * visualization purpose. It is not an audio recording interface and only returns partial and low
- * quality audio content. However, to protect privacy of certain audio data (e.g voice mail) the use
- * of the visualizer requires the permission android.permission.RECORD_AUDIO.
- * The audio session ID passed to the constructor indicates which audio content should be
- * visualized:
- * - If the session is 0, the audio output mix is visualized
- * - If the session is not 0, the audio from a particular MediaPlayer or AudioTrack
- *   using this audio session is visualized
- * Two types of representation of audio content can be captured:
- * - Waveform data: consecutive 8-bit (unsigned) mono samples by using the getWaveForm() method
- * - Frequency data: 8-bit magnitude FFT by using the getFft() method
- *
- * The length of the capture can be retrieved or specified by calling respectively
- * getCaptureSize() and setCaptureSize() methods. Note that the size of the FFT
- * is half of the specified capture size but both sides of the spectrum are returned yielding in a
- * number of bytes equal to the capture size. The capture size must be a power of 2 in the range
- * returned by getMinCaptureSize() and getMaxCaptureSize().
- * In addition to the polling capture mode, a callback mode is also available by installing a
- * callback function by use of the setCaptureCallBack() method. The rate at which the callback
- * is called as well as the type of data returned is specified.
- * Before capturing data, the Visualizer must be enabled by calling the setEnabled() method.
- * When data capture is not needed any more, the Visualizer should be disabled.

-     *                     (TODO: Check direct output after flags can be used in Java AudioTrack.)
-     * format:             Audio format. For mixed tracks, any PCM format supported by server is OK.
-     *                     For direct and offloaded tracks, the possible format(s) depends on the
-     *                     output sink.
-     *                     (TODO: How can we check whether a format is supported?)
-     * channelMask:        Channel mask, such that audio_is_output_channel(channelMask) is true.
-     * cbf:                Callback function. If not null, this function is called periodically
-     *                     to provide new data and inform of marker, position updates, etc.
-     * user:               Context for use by the callback receiver.
-     * frameCount:         Minimum size of track PCM buffer in frames. This defines the
-     *                     application's contribution to the latency of the track.
-     *                     The actual size selected by the JAudioTrack could be larger if the
-     *                     requested size is not compatible with current audio HAL configuration.
-     *                     Zero means to use a default value.
-     * sessionId:          Specific session ID, or zero to use default.
-     * pAttributes:        If not NULL, supersedes streamType for use case selection.
-     * maxRequiredSpeed:   For PCM tracks, this creates an appropriate buffer size that will allow
-     *                     maxRequiredSpeed playback. Values less than 1.0f and greater than

-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade

-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
