CDLongAudioSource Class Reference

Inherits from	NSObject
Conforms to	AVAudioPlayerDelegate CDAudioInterruptProtocol
Declared in	CDAudioManager.h

Overview

CDLongAudioSource represents an audio source that has a long duration which makes it costly to load into memory for playback as an effect using CDSoundEngine. Examples include background music and narration tracks. The audio file may or may not be compressed. Bear in mind that current iDevices can only use hardware to decode a single compressed audio file at a time and playing multiple compressed files will result in a performance drop as software decompression will take place.
