Nope. What you can record to depends on the framework you're using.
With AudioUnits, you can only record to linear pcm. AVAudioRecorder
allows you to set encoder settings, but I don't know what the output
format is. I suspect it's the same as for AudioQueues. These are
detailed here:

Once you've recorded your data, you can save it to file and there you
have the additional options I wrote about earlier.
