Thanks! It took me a while to figure out how to get this format info, but I think it is working. I'm using the "master channel" of the AudioDevice to get the AudioStream to get the format. Is this correct? I can't find any documentation on what exactly a master channel is.

In AudioHardware.h there are format descriptor properties for the virtual and physical formats of the device. The virtual format is normally the canonical Float32. The physical format is whatever the device is using.

The AudioOutputUnit nicely provides a stream of Float32 samples. But I would like to choose the bit-depth of the file I am recording to based on the precision of the input device. So how can I determine this precision? The stream format for the input device always says that precision is 32 bits per channel since it is a floating point stream.
