BufCombN

Comb 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
// These examples compare the variants, so that you can hear the difference in interpolation

// allocate buffer
val b = Buffer.alloc(s, (0.01 * s.sampleRate).toInt.nextPowerOfTwo)

// Comb used as a resonator. The resonant fundamental is equal to
// reciprocal of the delay time.
play { BufCombN.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), 0.2) }

play { BufCombL.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), 0.2) }

play { BufCombC.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), 0.2) }

// with negative feedback
play { BufCombN.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), -0.2) }

play { BufCombL.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), -0.2) }

play { BufCombC.ar(b.id, WhiteNoise.ar(0.01), XLine.kr(0.0001, 0.01, 20), -0.2) }

b.free()   // do this after the synths have ended

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

play { BufCombN.ar(b.id, Decay.ar(Dust.ar(1) * 0.5, 0.2) * WhiteNoise.ar, 0.2, 3) }

b.free()   // do this after the synth has ended

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.
