 // Audio rendering unit utilizing an AudioRendererSink to output data.
 //
 // This class lives inside three threads during it's lifetime, namely:
 // 1. Render thread
 //    Where the object is created.
 // 2. Media thread (provided via constructor)
 //    All AudioDecoder methods are called on this thread.
 // 3. Audio thread created by the AudioRendererSink.
 //    Render() is called here where audio data is decoded into raw PCM data.
 //
 // AudioRendererImpl talks to an AudioRendererAlgorithm that takes care of
 // queueing audio data and stretching/shrinking audio data when playback rate !=
 // 1.0 or 0.0.
