MediaWare Solutions MPEG SDK

The SoundBite class represents a decodeable/playable unit of sound from the MPEG audio stream. It is roughly parallel to a "picture" in the video stream.

The SoundBite class is the abstract class that defines the number of samples, the number of channels, and the sample frequency of the unit. Derived classes instantiate a unit of audio for different audio formats.
