I have a working AUGraph with a mixer unit connected to a RemoteIO
unit, which sends output to the speaker as expected. I'd like to
write the resulting mix to a file. I am trying to follow this
strategy:
- replace the remoteIO unit with a generic io unit
- put a renderProc on the generic io unit that writes the mixed stream
to a file
- start the AUGraph
I have a property change listener on the generic io unit which indeed
shows me that the unit is being started, but my renderProcs on the
mixer input buses and the one on the generic IO unit are not being
invoked
Is what I'm trying to do incorrect, or have I just missed some
configuration step?
thanks
wil
