You have to have all of your sound going through that graph.
No problem with that at all, that's actually the very thing I want to
-- all my sound going to the graph at its input point (there'd be only
one for the moment).
All I need for that is one "generator AU" which would automatically
get all the "standard output": whomever renders any sound to the
standard output device, he would actually render it to this unit.
Darn, that's why the devices are virtual to allow such things, is it
not? It seemed a very basic (and easy) thing to do... only I can't
find anything like that, and... you say it does not exist at all?!?
Huh. How naïve of me.
So, you can't use QT - because it uses its only audio engine to
output audio,
I fear there's no way I could dodge QT, for one of the applications'
features is playing movies of all kinds (well I could very
theoretically use ffmpeg or so, but the sheer amount of work needed to
change all the code renders the though preposterous).
you can't use NSBeep as it uses a different mechanism, you can't use
the NSSpeech... guy on its own (you can use the augn speech audio
unit though)
...
There is no current way to capture all/any of the audio output of
your application
Well thanks a lot for the information, at least I can stop wasting my
time searching for the solution :(
But dammit all -- this inexplainable limitation makes the whole Core
Audio pretty much unusable! What the H did they think of designing the
stuff?!? :-O
It would be all well and swell if I designed a brand-new app, but I
got some hundred-odd thousands of existing lines including 3rd party
plugins whose NSBeep and QTMovie and NSSpeechSynth and dunno-what-else
using code I don't control -- audio output of which, all going to the
abstract "default output device", I'd need to process uniformly and
consistently in a way CA seems to be best for.
(What I actually need is simply to process the stereo sound to make it
multi-channel based on comparatively plain rules -- at the moment I am
pretty positive the Matrix Mixer AU's all I need, in future I'd add
some extras based on 3D mixer.)
Ick :( So much for the shiny new technology :(
Best,
