Processing stereo data?


  • Subject: Processing stereo data?
  • From: Rick Mann <email@hidden>

I'm working through the Audio Unit Programming Guide Simple Effect tutorial. I've created an Audio Unit Effect from Xcode 2.3.5 stationery.

The comments in the Process() method say that num channels is always 1, and that it requires non-interleaved format for all inputs and outputs.

But then when they advance the input sample pointer by inNumChannels (which is 1), the comment says "stereo, we're advancing 2 samples".

In any case, my effect only gets one channel. How can I work with stereo data? Is that covered later in the tutorial?

TIA,
Rick
