BFEncode2 Ambisonic B format encoder

BFEncode2.ar(in, point_x, point_y, elevation, gain)

in - input signal

point_x - a point in the x axis

point_y - a point in the y axis

elevation - in radians, -0.5pi to +0.5pi

gain - a control rate level input.

x, y positions-

0 -1 behind

0 1 in front

-1 0 right

1 0 left

Output channels are in order W,X,Y,Z.

Because of the way the W component is scaled, it is recommended that you only decode with BFDecode1 and it's methods.

s=Server.local.boot;

// You'll only hear the first two channels on a stereo setup.

({

#w, x, y, z = BFEncode2.ar(WhiteNoise.ar, MouseX.kr(-20, 20), MouseY.kr(20, -20), 0, 0.3);

//decode for 4 channels

BFDecode1.ar(w, x, y, z, [-0.25pi, 0.25pi, 0.75pi, 1.25pi], 0);

}.scope(4));
