BufWr

A UGen that writes a signal to a buffer, using an index pointer.

Warning: if the supplied bufID refers to a buffer whose number of channels differs from those of the input signal, the UGen will fail silently.

An alternative to BufWr is RecordBuf . While RecordBuf advances the index into the buffer by itself, BufWr only moves its write point by the index input, making it possible to adjust the writing speed or to access the buffer in a non-linear way. RecordBuf can determine the end of the buffer and issue a done-action.

Examples

// record and playback
// a two second mono buffer
val b = Buffer.alloc(s, numFrames = s.sampleRate.toInt * 2)

val y = play {
  val sig  = SinOsc.ar(LFNoise1.kr(2).madd(300, 400)) * 0.1
  val rate = "rate" kr 1
  BufWr.ar(in = sig, buf = b.id, index =
    Phasor.ar(speed = BufRateScale.kr(b.id) * rate, lo = 0, hi = BufFrames.kr(b.id)))
  0.0 // quiet
}

// read it with a BufRd
val x = play {
  val rate = "rate" kr 1
  BufRd.ar(1, buf = b.id, index =
    Phasor.ar(speed = BufRateScale.kr(b.id) * rate, lo = 0, hi = BufFrames.kr(b.id)))
}

x.set("rate" -> 5)
y.set("rate" -> 3)
x.set("rate" -> 2)
