Thanks, Doug - though as you say, AudioUnitGetProperty is used to
fill in the ASBD based on the characteristics of the synth, which is
the DLS synth. Then that ASBD is applied to the external file using
ExtAudioFileSetProperty. The sample code doesn't include any other
way of setting the output format, aside from specifying the type
(WAVE, AIFF, CAF, etc.). I don't see why this sample code would
work, given what you say below. Actually I have no proof that the
sample code does work, I suppose.
In any event I've tried specifying CAF file output too, but
ExtAudioFileCreateNew still fails with the unsupported format error
with the ASBD filled out as per the sample code. Is the sample code
missing some way to set up a separate ASBD for the output file?
Sorry, I have no idea of what sample code you are looking at or where
to find it. I do, however, have a copy of CAAudioUnitOutputCapturer.h
in front of me. What is the audio data format being passed to the
constructor? If you get an error even when specifying CAF, then most
likely the data format is not correctly filled out.
