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. |
