OK, I looked up and down the headers, all the SDK documentation, and
searched apples site. I can't find
documentation on how to do this! I know you use:
err=AudioUnitSetProperty(au_mixer,kAudioUnitProperty_StreamFormat,kAudio
UnitScope_Input,i,&????,sizeof(????));
But I have NO idea what the constants are ... I can't find then
anywhere! Note the ????. What goes there?
Also, I noticed I seem to be doing things a ... "old" way (v1 version
v2). That might also be causing me problems (I'm using
kAudioUnitProperty_SetInputCallback). I'm gonna understand this if it
kills me!!
