In our application I need 8khz, 1 channel, 16bit audio from the input device (mic) .. and everything works fine when the hardware device supports those settings. The chalenge is when it does not, and rather than doing downsampleing (and channel deinterleaving?) by hand, I figure there must be a way to do this in core audio.

Sounds like you need an AudioConverter.
Or if you're writing the audio to a file, ExtAudioFile will handle format conversions for you automatically.
