No, it is not possible to do this outside of the kernel.

Can you explain what you mean by this?
What I would like to achieve is to create an audio device that would
act as
a sort of "proxy" for the other audio devices on the machine. So the
user would
be able to select my device in order to record from, say, either the
buillt-in audio
device or the iMic, etc. My "fake" device would then just pass on the
data from
the "real" device after performing some processing. Same goes for
playback...
If possible, I would like to stay in user space for that (Fig. 2-15 in
/Developer/Documentation/MusicAudio/Reference/CoreAudio/
core_audio_intro/index.html
seems to say that it is indeed possible), since I have no experience
with kernel
programming.
To think about it, it seems that this kind of stuff could be achieved
with an APE
module, does that sound reasonable? Thanks,
