summary:: Comb delay line with linear interpolation.
related:: Classes/CombC, Classes/CombN, Classes/BufCombL
categories:: UGens>Delays
Description::
Comb delay line with linear interpolation. See also link::Classes/CombN::
which uses no interpolation, and link::Classes/CombC:: which uses cubic
interpolation. Cubic interpolation is more computationally expensive
than linear, but more accurate.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::maxdelaytime
The maximum delay time in seconds. Used to initialize the delay buffer size.
argument::delaytime
Delay time in seconds.
argument::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.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
// These examples compare the variants, so that you can hear the difference in interpolation
// Comb used as a resonator. The resonant fundamental is equal to
// reciprocal of the delay time.
{ CombN.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), 0.2) }.play;
{ CombL.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), 0.2) }.play;
{ CombC.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), 0.2) }.play;
// with negative feedback:
{ CombN.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), -0.2) }.play;
{ CombL.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), -0.2) }.play;
{ CombC.ar(WhiteNoise.ar(0.01), 0.01, XLine.kr(0.0001, 0.01, 20), -0.2) }.play;
// used as an echo.
{ CombL.ar(Decay.ar(Dust.ar(1,0.5), 0.2, WhiteNoise.ar), 0.2, 0.2, 3) }.play;
