object VBAP extends ProductReader[VBAP] with Serializable

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();

This is a third-party UGen (VBAPUGens).

  4. 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.
