Ah, one caveat: the exporter component in question has to implement
MovieExportFromProceduresToDataRef. All of ours do (export to .mov,
.mp4, .3g, .avi, .aif, .wav, .au, etc, etc). Don't know about OGG,
AAC, LAME.

Come on over to the quicktime-api list, and we can discuss it there.
You _can_ use QuickTime's export functionality "standalone", having
the exporter component call you for input data (as well as for details
of what the output format should be).

i have raw audio samples in memory, I use CoreAudio to play the
samples.
I'd like to use QuickTime Export to save it to disk (ergo: have
access to any installed QT export components, eg: OGG, AAC, LAME)
Must I first save the audio to a QuickTime Movie file, then "export"
that movie? or can I "stream" it in one shot, right out of memory,
without any pre-processing?
Am I barking up the wrong tree here?
Or, rather, how do I do what I want?
Thanks.
