Answer 1

OK, I've successfully resolved this problem.

The problem is I should not construct the AudioStreamBasicDescription struct myself. But use the one provided by prepare callback of AudioProcessorTap .

static void tap_PrepareCallback(MTAudioProcessingTapRef tap, CMItemCount maxFrames, const AudioStreamBasicDescription *processingFormat) //retain this one
