VBAP

A UGen for Vector Base Amplitude Panning (VBAP). This allows for equal power panning of a source over an arbitrary array of equidistant speakers. Normally this would be a ring, a dome, or partial dome.

VBAP was created by Ville Pulkki. For more information on VBAP see http://www.acoustics.hut.fi/research/cat/vbap/ This version of VBAP for SC was ported from the ver. 0.99 PD code by Scott Wilson.

Examples

// two-dimensional
val a = VBAPSetup(2, Seq(0, 45, 90, 135, 180, -135, -90, -45)) // 8 channel ring

val b = Buffer.alloc(s, a.bufferData.size)
b.setn(a.bufferData)

val x = play {
  val azi = "azi".kr(0)
  val ele = "ele".kr(0)
  val spr = "spr".kr(0)
  VBAP.ar(8, PinkNoise.ar(0.2), b.id, azi, ele, spr)
}

// test them out
x.set("azi" -> a.directions(1).azi)
x.set("azi" -> a.directions(2).azi)
x.set("azi" -> a.directions(3).azi)
// ...
x.set("azi" -> a.directions(7).azi)
x.set("azi" -> a.directions(0).azi)

// try the spread
x.set("spr" ->  20)
x.set("spr" -> 100) // all speakers

x.free(); b.free();

def ar(numChannels: Int, in: GE, buf: GE, azimuth: GE = 0, elevation: GE = 1, spread: GE = 0): VBAP

numChannels
the number of output channels
in
the signal to be panned
buf
id of a buffer containing data calculated by VBAPSetup . Its number of channels must correspond to numChannels
azimuth
+/- 180° from the median plane (i.e. straight ahead)
elevation
+/- 90° from the azimuth plane
spread
A value from 0-100. When 0, if the signal is panned exactly to a speaker location the signal is only on that speaker. At values higher than 0, the signal will always be on more than one speaker. This can smooth the panning effect by making localisation blur more constant.
