One method that quite a few people use is the excellent SoundFlower
software. This is just a FIFO output component that you write into
and can read from. It's essentially a loop-back audio device, so you
set the output of your generator to SoundFlower, and then open the
SoundFlower input via the HAL and slurp sample vectors, pushing the
output to the desired final destination. You should be able to easily
accomplish this with Max/MSP (by setting the device of a dac~ object
to the soundflower and similarly the device of an adc~ object to the
same soundflower). In your case, you may have to modify this by
setting the default system out to soundflower and setting the output
of the dac~ to the output component you wish to hear the sound on in
Max.

I apologize for bringing up a tangent question about the 'output
capture' question on this list, as I know this is more in line for a
quicktime question for one of their lists, but part of it has to do
with CoreAudio.
I do in fact program in CoreAudio, but I also use the Max/MSP/Jitter
application too for things I need to rapidly prototype. One of the
issues they point out with QT7+ is that the output of QuickTime
movies goes directly to CoreAudio where as in previous versions, it
could be siphoned off into their max/msp environment. When I asked
them about it, they said it was a core change of QT that caused this.
My question is, are their any mechanisms to how QT at least output
to different locations or from now on, there are only plans to
output directly to CoreAudio? I have written a video mixer that I'd
love to implement some audio enhancements to (compression,
excitement, etc).
When someone mentioned DRM, this is the only thing I could think
of. Since QT is being used inside another program, I can't imagine
it would be a small number of people that would want this ability
(as in using QT libraries instead of recreating the wheel).
Again, sorry to steer off-topic here, but I find the people here
INCREDIBLY helpful and it does have a portion to do with CoreAudio
(at least from a QT standpoint).
Thanks!
