I'm writing because an engineer friend of mine is looking for two
utility AU plugins and they're beyond my ability to figure out (I'm
not very smart, just sort of cunning about making things sound good).
One- he wants to take in an input, and then also a sidechain input,
and display the latency difference between them (they'd be related
sounds like a snare mic and a pair of overhead mics). I could sort
out a way to have the plugin interpret non-identical inputs (I've
done a similar thing for tracking tape azimuth) but I cannot figure
out how to open a sidechain input. I don't even know what a callback
is- waaay out of my depth doing anything but playing with sample
buffers given to me by already built example code.
Is there any such example code that opens and (for instance) does
something like the 'gain' AU example only with a sidechain included?
I may need to hire someone to set that up for me though it's going to
be a couple months before I can afford it. If it matters, the
'latency' AU I'm talking about would be free.
Second and probably less feasible- he would like to 'wrap' existing
AUs in such a way that he can pass a dry signal parallel to the AU
and mix it in at the end. It seems like this would require writing an
AU that is itself an AU host. How monumental is this task? I already
know I can't do it myself but I'm wondering what to tell him. The
other possibility would be finding some way to take an AU, have it
make some connection to a matching other AU, and have the one pass
data to the other. However, that would totally ignore whatever
latency the 'middle' AU would have, plus I don't even know if it's
possible. I don't mean AUNetSend and Receive, I am thinking more like
the other idea, of opening additional channels.
I'm sorry if this is rather incoherent but I'm out of my depth. If
anybody is game for making a "gain example" AU that opens sidechain
inputs that I could build on, even if I need to hire you to do it,
talk to me and I'll try to work out what I can pay. I'm sure this is
very clear and straightforward to some people but they're not me, and
I find I have to have the framework there or I get swamped by the
parts of it I don't understand...
