class:: BRF
summary:: 2nd order Butterworth band reject filter.
related:: Classes/BPF, Classes/HPF, Classes/LPF
categories:: UGens>Filters>Linear
Description::
A second order band reject filter.
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).
Examples::
code::
{ BRF.ar(Saw.ar(200,0.1), FSinOsc.kr(XLine.kr(0.7,300,20),0,3800,4000), 0.3) }.play;
{ BRF.ar(Saw.ar(200,0.5), MouseX.kr(100, 10000, 1), 0.3) }.play;
// BRF on control signals:
(
{ var vib = BRF.kr(SinOsc.kr([1, 3, 10], 0, [1, 0.5, 0.25]).sum, MouseX.kr(1, 10, 1), 0.3);
SinOsc.ar(vib * 200 + 600) * 0.2 }.play;
)
