hi everyone:
Does anyone know a callback function that tell the host application
(mine is garageband) finishes exporting the song? I writing to a
Audio unit can record its own output into an an audio file. I am
using extended audio file service.
I need to dispose the audio file object in order to complete the audio
file it writes after the application finishes exporting the whole
song. (Only you can play out the audio file after you dispose the
audio file object). currently I put this
'ExtAudioFileDispose(outFile)' in the destructor of my audio unit
which means after exporting the song I need to quit my audio unit in
garageband before the audio file could be played out. I wander if
there is notification from the host telling me 'oh i finished the
exporting', then i can dispose the audio object just after.
Thanks.
Tony
