you indicated that you're using MTCoreAudio, so take a look at the "AudioBufferList Utility Functions" -- specifically MTAudioBufferListCopy(). also, if you're using MTAudioBuffers or MTConversionBuffers, they will do the right thing copying between AudioBufferLists with mismatched channel counts or stream layouts.

Hi,
My cheap USB mic is one channel output but the headphones are two channels input. I'm playing with the "recordotron" sample code and have recorded x seconds of audio to a buffer when the buffer is played back it's double speed. How do I convert the existing buffer from 1 channel to 2 channels so it plays properly? All the sample code I've seen wants to convert on the fly as 'play thru'.
Regards,
Paul
