Hi,
I'm trying to understand how the AUHAL system works. But an
understanding of this stuff is being quite elusive.
For example, I'd like to implement a realtime filter using the input
and outputs. So to do this, is the following the correct chain of
events?
1) Find and open my filter AU component
2) set up my output device
3) add an IOProc to the output device pointing back to my filter
4) set up the input device
5) enable it with kAudioOutputUnitProperty_EnableIO
6) set the input device to output to my filter
(I might be off on the terminology for #6)
7) start the output device
Is that right? If not, what am I missing?
Thanks,
-Chilton
