Resonant filter.
Source: Filter.sc

Description

This is the same as Ringz , except that it has a constant gain at 0 dB instead of being constant skirt.

It is a two pole resonant filter with zeroes at

Based on K. Steiglitz, "A Note on Constant-Gain Digital Resonators", Computer Music Journal, vol 18, no. 4, pp. 8-10, Winter 1994.

Class Methods

Resonz.ar(in: 0.0, freq: 440.0, bwr: 1.0, mul: 1.0, add: 0.0)

Resonz.kr(in: 0.0, freq: 440.0, bwr: 1.0, mul: 1.0, add: 0.0)

Arguments:

in

The input signal.

freq

Resonant 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!

bwr

Bandwidth ratio (reciprocal of Q). rq = bandwidth / centerFreq.

The reciprocal of Q is used rather than Q because it saves a divide operation inside the unit generator.

mul

Output will be multiplied by this value.

add

This value will be added to the output.
