class:: RHPF
summary:: A resonant high pass filter.
related:: Classes/Formlet, Classes/RLPF, Classes/Resonz, Classes/Ringz
categories:: UGens>Filters>Linear
Description::
A resonant high pass 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).
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
{ RHPF.ar(Saw.ar(200,0.1), FSinOsc.kr(XLine.kr(0.7,300,20), 0, 3600, 4000), 0.2) }.play;
(
{ var ctl = RHPF.kr(LFSaw.kr(2), SinOsc.kr(XLine.kr(0.07,30,20), 0, 35, 40), 0.05);
SinOsc.ar(ctl * 200 + 500);
}.play;
)
