summary:: A resonant low pass filter.
related:: Classes/Formlet, Classes/RHPF, Classes/Resonz, Classes/Ringz
categories:: UGens>Filters>Linear
Description::
A resonant low pass filter.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::freq
Cuttoff frequency in Hertz.
argument::rq
The reciprocal of Q (bandwidth / cutoffFreq).
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
{ RLPF.ar(Saw.ar(200,0.1), FSinOsc.kr(XLine.kr(0.7,300,20),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;
)
(
{ var ctl = RLPF.ar(Saw.ar(5,0.1), MouseX.kr(2, 200, 1), MouseY.kr(0.01, 1, 1));
SinOsc.ar(ctl * 200 + 400) * 0.1;
}.play;
