Roland,

The following will work as an export function, not in conjunction with output simultaneously going to standard output...

- build your AUGraph using the generic output device (kAudioUnitSubType_GenericOutput) - setup your output format, tell the graph about it - create a file and set the format there also (CAAudioFile makes it easy) - setup a buffer (AUOutputBL) - do until your source has all been 'played' ... - prepare the buffer - call AudioUnitRender on the output unit to fill the buffer - call outputFile.Write to put the buffer into the file - close the file

These steps are only a bare outline, of course. There probably are other ways to do this sort of thing...

I have a working program that lets me compose music and send output to the Mac standard output (pleakers). How can I modify it to send output to an aiff or mpeg file?
