Comb delay line with linear interpolation.
Source: Delays.sc

Description

Comb delay line with linear interpolation. See also CombNwhich uses no interpolation, and CombC which uses cubic interpolation. Cubic interpolation is more computationally expensive than linear, but more accurate.

The feedback coefficient is given by the equation fb == 0.001 ** (delay / decay.abs) * decay.sign where 0.001 is -60 dBFS.

Class Methods

CombL.ar(in: 0.0, maxdelaytime: 0.2, delaytime: 0.2, decaytime: 1.0, mul: 1.0, add: 0.0)

From superclass: CombN

CombL.kr(in: 0.0, maxdelaytime: 0.2, delaytime: 0.2, decaytime: 1.0, mul: 1.0, add: 0.0)

From superclass: CombN

Arguments:

in

The input signal.

maxdelaytime

The maximum delay time in seconds. Used to initialize the delay buffer size.

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.

Large decay times are sensitive to DC bias, so use a LeakDC if this is an issue.

Infinite decay times are permitted. A decay time of inf leads to a feedback coefficient of 1, and a decay time of -inf leads to a feedback coefficient of -1.

mul

Output will be multiplied by this value.

add

This value will be added to the output.
