List:
I want to write the output from a relatively complex AUGraph
(including DLSSynths, effects, mixer, output, etc.) to an audio file
while it is playing.
I have not been able to figure out how to stream the audio being
generated by the AUGraph to an ExtAudioFile. The Core Audio examples
that write audio files either use the Default input device (i.e. mic )
or they stream data from existing audio files. When I try to
duplicate this process with one of the Audio Units in my AUgraph (i.e.
trying to set up a render callback on the outputUnit or on one of the
other audiounits) I am not able to get the data through the callback
function and out to the audio file.
Am I going about this the right way, and if not, can someone point me
in the right direction or point me to a code snippet that might help...
Thanks, Keith Hamel
