I've developed a commercial application that outputs MIDI instrumental
sounds combined with the playback of AIFF files. I'd like to be able
to record the app's output to a digital audio file like AIFF or MP3,
etc. I've looked at Apple's docs to figure out how to do it but can't
seem to find anything on point. There's a lot of info for recording
from external devices like a microphone, but doesn't seem to be
anything on recording the sound generated from within the app itself.
I've used "soundflower" with partial success to wrap the audio output
back around to the default input, but I don't think this is a viable
solution since the app is distributed to users with all types of
computer knowledge.
Working with the AUHAL might be a solution, but I'm not sure that what
I want is just connecting the output back to the input. It seems the
data is already there inside QuickTime and I just need to figure out
how to access it and use it directly as the input to my recording code
(I've been using the QuickTime movie Sequence Grabber for recording).
Does anyone have any thoughts on how I might accomplish this?
Thanks!
John
