AUTimePitchTest demonstrates how to build an Audio Unit Graph connecting an AUConverter to a MultiChannel Mixer to the AUTimePitch audio unit then to the Default Output unit.

The AUTimePitch unit can be used to speed up or slow down audio data without changing pitch to facilitate for example, the playing back of an audio book faster or slower than real-time. The same concepts and Core Audio specific APIs demonstrated in this sample may be applied to and used with iOS applications with only minor modification for available audio unit types.
