BiPanB2 2D Ambisonic B-format panner
BiPanB2.kr(inA, inB, azimuth, gain)
Encode a two channel signal to two dimensional ambisonic B-format.
This puts two channels at opposite poles of a 2D ambisonic field.
This is one way to map a stereo sound onto a soundfield.
It is equivalent to:
PanB2(inA, azimuth, gain) + PanB2(inB, azimuth + 1, gain)
inA - input signal A
inB - input signal B
azimuth - position around the circle from -1 to +1.
-1 is behind, -0.5 is left, 0 is forward, +0.5 is right, +1 is behind.
gain - amplitude control
var w, x, y, p, q, a, b, c, d;
p = LFSaw.ar(200);
q = LFSaw.ar(301);
// B-format encode
#w, x, y = BiPanB2.ar(p, q, MouseX.kr(-1,1), 0.1);
// B-format decode to quad
#a, b, c, d = DecodeB2.ar(4, w, x, y);
