I’m working with stereo soruces to be placed inside a multi-speaker setup.
I know thata PanAz UGen doesn’t work with stereo input so I came out with this:
(
~nspeakers = 8;
~spotoffset = 1.0/~nspeakers;
s.options.numOutputBusChannels = ~nspeakers;
SynthDef(\source, {
|out=0|
var sig;
var pos = SinOsc.kr(0.5); // autopan
sig = SinOsc.ar(440, mul:0.25);
Out.ar(out, Pan2.ar(sig, pos));
}).add;
SynthDef(\outputstage, {
|in=0, pos=0, orientation=0.0, w=2|
var sig = In.ar(in, 2);
Out.ar(0, PanAz.ar(~nspeakers, sig[0], (pos - ~spotoffset), width:w, orientation:orientation ));
Out.ar(0, PanAz.ar(~nspeakers, sig[1], (pos + ~spotoffset), width:w, orientation:orientation ));
}).add;
)
(
c = Bus.audio(s, 2);
a = Synth(\outputstage, [\in, c]);
b = Synth(\source, [\out, c], a, \addBefore);
)
// make some modification
a.set(\pos, 0.375);
a.set(\orientation, 0.0);
Is there a better way to place a stereo source inside a 360/multi-speaker arrangement?
Thank you very much fro your support!
Besides, going from stereo to multichannel is an interesting demand which opens a field for experimenting with alternative methods. In my last pieces I splitted stereo signals into frequency bands, did MS-encoding and defined slightly differentiated movements for the results, which, I think, worked quite well. I might document that on occasion.
Is there any progress for this type of idea, I’m looking for something simpler and educative that can be little bit a less advanced to make static measurements by microphone input before playing?
