phaflangers.lib

Phasers and Flangers library. Its official prefix is pf.

This library provides a set of phaser and flanger effects based on delay-line modulation.

The Phaflangers library is organized into 1 section:

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 typical
  • curdel: 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

Test

pf = library("phaflangers.lib");
os = library("oscillators.lib");
flanger_mono_test = os.osc(440) : pf.flanger_mono(4096, 1024, 0.7, 0.25, 0);

(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 typical
  • curdel1: current dynamic delay for the left channel (not to exceed dmax)
  • curdel2: current dynamic delay for the right channel (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

Test

pf = library("phaflangers.lib");
os = library("oscillators.lib");
flanger_stereo_test = os.osc(440), os.osc(660) : pf.flanger_stereo(4096, 1024, 1536, 0.7, 0.25, 0);

(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 Hz
  • frqmin: approximate minimum frequency of first spectral notch in Hz
  • fratio: ratio of adjacent notch frequencies
  • frqmax: approximate maximum frequency of first spectral notch in Hz
  • speed: 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

Test

pf = library("phaflangers.lib");
os = library("oscillators.lib");
phaser2_mono_test = os.osc(330) : pf.phaser2_mono(4, 0.0, 50, 200, 1.5, 4000, 0.5, 0.8, 0.2, 0);
