Greyhole

A complex echo-like effect UGen, inspired by the classic Eventide effect of a similar name. The effect consists of a diffuser (like a mini-reverb) connected in a feedback system with a long modulated delay-line. Excels at producing spacey washes of sound.

Examples

// discrete
play {
  val src = LeakDC.ar(SplayAz.ar(2, Impulse.ar(Seq(1, 3, 5, 7, 9))))
  Greyhole.ar(
    inL = src\0, inR = src\1, delayTime = 0.1, damp = 0.1,
    feedback = 0.1, modDepth = 0.01, modFreq = 2)
}

// time modulation
play {
  val src = LeakDC.ar(SplayAz.ar(2, Impulse.ar(Seq(1, 3, 5, 7, 9))))
  val time = LFTri.kr(0.01).linexp(-1, 1, 0.05, 0.2)
  Greyhole.ar(
    inL = src\0, inR = src\1, delayTime = time, damp = 0.4,
    feedback = 0.99, modDepth = 0.01, modFreq = 2)
}

This is a third-party UGen (DEINDUGens).

inL
left input signal
inR
right input signal
delayTime
approximate delay time in seconds. (0.1..60)
damp
damping of high-frequencies as the delay decays. 0 is no damping, 1 is very strong damping (0..1)
size
scales the size of delay-lines, producing the impression of a larger or smaller space. Values below 1 can sound quite metallic. (0.5..5)
diff
shape of echo patterns produced by the diffuser. At very low values, the diffuser acts like a delay-line whose length is controlled by the size parameter. Medium values produce a slow build-up of echoes, giving the sound a reversed-like quality. Values of 0.707 or greater than produce smooth exponentially decaying echoes. (0..1)
feedback
amount of feedback through the system. Sets the number of repeating echoes. A setting of 1.0 produces infinite sustain. (0..1)
modDepth
depth of delay-line modulation. Use in combination with modFreq to produce chorus and pitch-variations in the echoes. (0..1)
modFreq
frequency of delay-line modulation. Use in combination with modDepth to produce chorus and pitch-variations in the echoes. (0..10)
