CombletN

Extension

Description

This is a comb filter whose impulse response is shaped like a Decay2 envelope. It is possible to control the attacktime and decaytime.

CombletN is equivalent to:CombN(in, freq, maxdelay, delaytime, decaytime) - CombN(in, freq, maxdelay, delaytime, risetime)

This allows very smooth reverb tails which begin with a slow rise rather than a dense echo pattern.( x = { var src = Decay2.ar(Impulse.ar(0.5, 0.99), 0.001, 0.1, PinkNoise.ar(1)); var comb = CombN.ar(src, 0.05, 0.05, 3); src + comb; }.play; ) x.free; ( x = { var src = Decay2.ar(Impulse.ar(0.5, 0.99), 0.001, 0.1, PinkNoise.ar(1)); var comb = CombletN.ar(src, 0.05, 0.05, 3, 1); src + comb; }.play; ) x.free; classmethods:: 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::risetime Decay time for the echoes that are subtracted to filter the attack of the response. If decaytime is negative, risetime should be too. argument::mul Output will be multiplied by this value. argument::add This value will be added to the output. discussion:: Note that if attacktime == decaytime then the signal cancels out, and if attacktime > decaytime then the response is inverted. CLASSMETHODS:: METHOD:: combClass the class of comb to use, which determines interpolation used: CombN for CombletN, CombL for CombletL, and CombC for CombletC. EXAMPLES:: code::
