I understand that I can use ExtAudioFileWriteAsync (etc.) to create a
file and stream the output of my graph to it. Here's the twist... I
don't want to hear the output while I'm writing the file. So, this
is more like Export to file. My graph currently consists of custom
generator unit(s), connected to a matrix mixer, connected to the
default output unit. I need the graph to generate the output because
I rely on event timing from the MusicSequence and the graph drives
this nicely.
I suppose for my export I could spoof the output unit by filling its
buffers with zeros while writing the actual data to file. This seems
a bit much. Am I missing something simple? Should I switch to AUHAL
rather than the default unit for the export? Is there support in
AUHAL for this that I've missed?
Thanks for any help.
