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;
)
