The Low Power Engine for Audio provides acceleration for common audio and voice
functions. The voice and audio engine provides a mechanism for rendering audio and
voice streams and tones from the operating system, applications to an audio or voice
codec, and ultimately to the speaker, headphones, or Bluetooth headsets.
