The PlayEffect sample code does exactly what you want. It takes input
coming from hardware and routes it through an AudioUnit to an output
device. It gets installed at
/Developer/Examples/CoreAudio/Services/PlayEffect by the SDK.
BTW, using an Output AudioUnit is the recommended way of dealing with
the HAL. It saves you from writing a lot of code required to be a good
HAL citizen. I would do it this way, just like Kurt's code and the
PlayEffect sample code, rather than using the HAL directly (at least
for output).

Hello,
Robert Grant pointed me to Kurt Revis' PlayBufferedSoundFile as a
sample on using AudioUnits. I have been a bit confused about adapting
Apple's samples for what I'd like to do, and his sample code is very
nice but still not quite on target.
Basically, I'm using IOProcs for input and output and would like to
take the audio input and run it through an AudioUnit effect. Is this
possible?
At a quick glance, it looks like Kurt's sample seems to chain the
output of the AudioUnit effect into an AudioUnit output, not using a
CoreAudio IOProc.
Anyone have any ideas? Thanks!
