... a question about Chris' answer:

"""
... the fact that AVFoundation capture doesn't work on the simulator.
"""

Is this a work-in-progress or a design decision?

I'm about to migrate my source code to support AVFoundation since it was said that the overlapping CoreAudio C API is going to retire to give way to AVFoundation. When something still does not work, maybe it's not the right time for migration yet? Apologies advance if I have any misunderstanding or this info can be found somewhere obvious.

Thanks,
Beinan

Check your code. I just ran CH10_iOSPlayThrough (the one with the Dalek effect) from the book's download code on Xcode 5.0.1's iOS 7 simulators (32- and 64-bit) and it worked just fine. This was on a 2008 Mac Pro with a USB mic.

Also check your OS X System Prefs -> Sound -> Input to make sure you're using the mic you think you're using.

Confusion may be from the fact that AVFoundation capture doesn't work on the simulator. But Core Audio capture has always worked for me on the simulator. Except when my code has sucked. Which happens a lot.
