object DecodeB2 extends ProductReader[DecodeB2] with Serializable
A two dimensional Ambisonics B-format decoding UGen. It assumes a set of
speakers in a regular polygon. The output channels are in clockwise order. The
position of the first speaker is specified by the orient argument.
Examples
// 4-channel rotation of opposite sounds play { val p = WhiteNoise.ar(0.05) // first source val q = Mix(LFSaw.ar(Seq(200, 200.37))) * 0.03 // second source // B-format encode 2 signals at opposite sides of the circle val enc = PanB2.ar(p, -0.5) + PanB2.ar(q, +0.5) val Seq(w, x, y) = (0 to 2).map(enc out _) val rot = Rotate2.ar(x, y, MouseX.kr(-1, +1)) // B-format decode to quad (front-left, front-right, rear-left, rear-right) DecodeB2.ar(4, w, rot.xr, rot.yr) }

orientation of the first channel. If zero, the first channel corresponds to the front vertex of the polygon. If the polygon does not have an edge at the front but a vertex, then an
orientof 0.5 indicates that the first channel corresponds to the speaker left of the center.
