 // AudioRendererAlgorithm buffers and transforms audio data. The owner of
 // this object provides audio data to the object through EnqueueBuffer() and
 // requests data from the buffer via FillBuffer().
 //
 // This class is *not* thread-safe. Calls to enqueue and retrieve data must be
 // locked if called from multiple threads.
 //
 // AudioRendererAlgorithm uses the Waveform Similarity Overlap and Add (WSOLA)
 // algorithm to stretch or compress audio data to meet playback speeds less than
 // or greater than the natural playback of the audio stream. The algorithm
 // preserves local properties of the audio, therefore, pitch and harmonics are
 // are preserved. See audio_renderer_algorith.cc for a more elaborate
 // description of the algorithm.
 //
 // Audio at very low or very high playback rates are muted to preserve quality.
