RLPF resonant low pass filter

Inherits from: Object : AbstractFunction : UGen : Filter

A resonant low pass filter.

RLPF.ar(in, freq, rq, mul, add)

RLPF.kr(in, freq, rq, mul, add)

in - input signal to be processed

freq - cutoff frequency.

rq - the reciprocal of Q. bandwidth / cutoffFreq.

// modulate cutoff frequency

{ RLPF.ar(Saw.ar(200, 0.1), FSinOsc.kr(XLine.kr(0.7, 300, 20), 0, 3600, 4000), 0.2) }.play;
