One more question if you don't mind: how do I get the example to
record in WAV file format? If I change line 139 in
DCAudioFileRecorder.cpp from kAudioFileM4AType to kAudioFileWAVEType
(or any other format) I get the error

[Session started at 2006-07-21 07:28:53 +0200.]
ExtAudioFileCreateNew FAILED! 1718449215 'fmt?'
Recording stoped.

I'm certain that I am missing something related to the corresponding
AudioStreamBasicDescription but I don't know where to look, can you
help?

The data format you're supplying for the file is incompatible with the file format. For WAVE you probably want a little-endian 8, 16, or 24-bit linear PCM format.

See my earlier message today for examples of how to determine the compatible data formats for a given file format.
