Audio

There are two distinct frameworks for recording and playing audio. The choice on which to use depends on the application:

■ MediaPlayer/MediaRecorder—This is the standard method to manipulate audio, but must be file- or stream-based data. Creates its own thread for processing. SoundPool utilizes this framework.
