Trying to use the CAAudioFile API to read either of these files:

http://www.igorlabs.com/etc/dirtsurface1C.wav
http://www.igorlabs.com/etc/fort_cruise_missile16_11_looped_i.wav

Both of these files read and play with Quicktime Player.

When I ask for the stream format, I get no error return but the stream format comes up cleared out and empty...

The AudioFile apparently doesn't understand the format... you're not doing anything wrong.


$ afinfo /tmp/dirtsurface1c.wav
File: /tmp/dirtsurface1c.wav
File type ID: WAVE
Data format: 0 ch, 0 Hz, ' ' (0x00000000) 0 bits/channel, 0 bytes/packet, 0 frames/packet, 0 bytes/frame
no channel layout.
audio bytes: 2816
audio packets: 2
maximum packet size: 1024
packet size upper bound: 1024
audio data file offset: 60
