A resonant low pass filter.
Source: Filter.sc
Subclasses: RHPF

Description

A resonant low pass filter.

Class Methods

RLPF.ar(in: 0, freq: 440, rq: 1, mul: 1, add: 0)

RLPF.kr(in: 0, freq: 440, rq: 1, mul: 1, add: 0)

Arguments:

in

The input signal.

freq

Cutoff frequency in Hertz. WARNING: due to the nature of its implementation frequency values close to 0 may cause glitches and/or extremely loud audio artifacts!

rq

The reciprocal of Q (bandwidth / cutoffFreq).

mul

Output will be multiplied by this value.

add

This value will be added to the output.

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


(
{ var ctl = RLPF.ar(Saw.ar(5, 0.1), 25, 0.03);
    SinOsc.ar(ctl * 200 + 400) * 0.1;
}.play;
