BufAllpassN

All pass delay line with no interpolation which uses a buffer for its internal memory.

Warning: For reasons of efficiency, the effective buffer size is the allocated size rounded down to the next power of two. For example, if 44100 samples are allocated, the maximum delay would be 32768 samples. Also note that the buffer must be monophonic.

Examples

// Compare interpolation types
// allocate buffer
val b = Buffer.alloc(s, (0.2 * s.sampleRate).toInt.nextPowerOfTwo)

// Since the allpass delay has no audible effect as a resonator on
// steady state sound ...
play { BufAllpassC.ar(b.id, WhiteNoise.ar(0.1), XLine.kr(0.0001, 0.01, 20), 0.2) }

// ...these examples add the input to the effected sound and compare variants so that you can hear
// the effect of the phase comb:
play {
  val z = WhiteNoise.ar(0.2)
  z + BufAllpassN.ar(b.id, z, XLine.kr(0.0001, 0.01, 20), 0.2)
}

play {
  val z = WhiteNoise.ar(0.2)
  z + BufAllpassL.ar(b.id, z, XLine.kr(0.0001, 0.01, 20), 0.2)
}

play {
  val z = WhiteNoise.ar(0.2)
  z + BufAllpassC.ar(b.id, z, XLine.kr(0.0001, 0.01, 20), 0.2)
}

b.free()  // after synths have been stopped

// Used as echo
val b = Buffer.alloc(s, (0.2 * s.sampleRate).toInt.nextPowerOfTwo)

// doesn't really sound different than Comb,
// but it outputs the input signal immediately (inverted) and the echoes
// are lower in amplitude.
play { BufAllpassN.ar(b.id, Decay.ar(Dust.ar(1) * 0.5, 0.2) * WhiteNoise.ar, 0.2, 3) }

b.free()

buf
Buffer id.
in
The input signal.
delayTime
Delay time in seconds.
decayTime
Time for the echoes to decay by 60 decibels. If this time is negative then the feedback coefficient will be negative, thus emphasizing only odd harmonics at an octave lower.
