DecodeB2

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 \ _)
  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)
}

y
Y (third) channel of B-format input signal
orient
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 orient of 0.5 indicates that the first channel corresponds to the speaker left of the center.
