BRF

2nd order Butterworth band reject filter.
Inherits from: BPF : Filter : PureUGen : UGen : AbstractFunction : Object

Description

A second order band reject filter.

Class Methods

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

From superclass: BPF

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

From superclass: BPF

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).

Examples

{ 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;
