phaflangers.lib
A library of phasor and flanger effects. Its official prefix is pf.
Functions Reference
(pf.)flanger_mono
Mono flanging effect.
Usage:
_ : flanger_mono(dmax,curdel,depth,fb,invert) : _
Where:
dmax: maximum delay-line length (power of 2) - 10 ms typicalcurdel: current dynamic delay (not to exceed dmax)depth: effect strength between 0 and 1 (1 typical)fb: feedback gain between 0 and 1 (0 typical)invert: 0 for normal, 1 to invert sign of flanging sum
Reference
(pf.)flanger_stereo
Stereo flanging effect.
flanger_stereo is a standard Faust function.
Usage:
_,_ : flanger_stereo(dmax,curdel1,curdel2,depth,fb,invert) : _,_
Where:
dmax: maximum delay-line length (power of 2) - 10 ms typicalcurdel: current dynamic delay (not to exceed dmax)depth: effect strength between 0 and 1 (1 typical)fb: feedback gain between 0 and 1 (0 typical)invert: 0 for normal, 1 to invert sign of flanging sum
Reference
(pf.)phaser2_mono
Mono phasing effect.
Phaser
_ : phaser2_mono(Notches,phase,width,frqmin,fratio,frqmax,speed,depth,fb,invert) : _
Where:
Notches: number of spectral notches (MACRO ARGUMENT - not a signal)phase: phase of the oscillator (0-1)width: approximate width of spectral notches in Hzfrqmin: approximate minimum frequency of first spectral notch in Hzfratio: ratio of adjacent notch frequenciesfrqmax: approximate maximum frequency of first spectral notch in Hzspeed: LFO frequency in Hz (rate of periodic notch sweep cycles)depth: effect strength between 0 and 1 (1 typical) (aka "intensity") when depth=2, "vibrato mode" is obtained (pure allpass chain)fb: feedback gain between -1 and 1 (0 typical)invert: 0 for normal, 1 to invert sign of flanging sum
