What is the difference between CAStreamBasicDescription and AudioStreamBasicDescription?

audiounit, core-audio, ios

Solution

CAStreamBasicDescription is just a wrapper class around AudioStreamBasicDescription. Just look at the .h file usually located at: /Developer/Extras/CoreAudio/PublicUtility/

I usually don't use CAStreamBasicDescription, but use AudioStreamBasicDescription directly. If you are looking for little help on how to fill the AudioStreamBasicDescription structure just use the function FillOutASBDForLPCM.
