Description

A resonant high pass filter.

Class Methods

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

From superclass: RLPF

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

From superclass: RLPF

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).

mul

Output will be multiplied by this value.

add

This value will be added to the output.
