Shaun, couldn't you just use Jack OS X to do the same as the
forthcoming audio unit? It also provides an AU (or VST) plugin to
route inserts as well...
I tried Jack a while ago, early in my development of MacFOH, and it
worked okay but they had some conflicts. I'll see if I can make it
work again when I get the chance. I think Jack is a great tool!
One of the benefits of MacFOH being able to patch into a recording app
like Logic at various points in the chain is that you can see exactly
how you are changing the signal path at each point, as well as
measuring sample-accurate latency and delay values, visualizing the
Transfer Function or Impulse Response between arbitrary inserts, and of
course watching the frequency response... and it does this with
extremely low CPU hit; it maintains full screen refresh rates with
dozens of channels under analysis, displayed in one or multiple
windows. I have a 64x64 channel audio matrix I/O and several other
interfaces, and I've run 128 channels in a single RTA window which
maintained about 20 fps. Even while Xcode is slamming both CPU's to
100% during a compile, MacFOH running at the same time rarely drops a
frame with 8-24 channels running. I leave at least one MacFOH analyzer
going nearly all the time, during Photoshop'ing, email, whatever. I
even find it hard to listen to the radio without visualization,
anymore... ;-)
BTW, nice looking app!!
Thanks! I have some 3D analyzer displays that I'm working on, too. I
can't wait... this is one of those app's that's been fun to write, but
a lot of work, and now I spend too much time just playing with it
because it's so cool. Nice to have for AU development as well as for
recording & mixing. I've got more work to do on my AU shell and the
phantom audio driver, but expect to release them in 1st qtr 2005.
