Playing back multiple audio files simultaneously
I am trying to play back multiple audio files in sync with one another. I tried using multiple AEAudioUnitFilePlayer instances, but the tracks did not start together. Then I tried using AUAudioFilePlayer directly, but I kept getting an error when I tried to add more than one ScheduledAudioFileRegion via kAudioUnitProperty_ScheduledFileRegion. Any other suggestions on how this might be accomplished? Is there a way to force all the tracks to start playback at the same time via timecode or something similar?
