|
classmethods::
|
|
|
|
method::ar, kr
|
|
|
|
argument::in
|
|
|
|
The input signal.
|
|
|
|
|
|
argument::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!
|
|
|
|
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), 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;

(
|
|
{ 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;
