BHiPass4 | SuperCollider 3.12.2 Help

Description

The B equalization suite is based on the Second Order Section (SOS) biquad UGen.

NOTE: Biquad coefficient calculations imply certain amount of CPU overhead. These plugin UGens contain optimizations such that the coefficients get updated only when there has been a change to one of the filter's parameters. This can cause spikes in CPU performance and should be considered when using several of these units.

[1] this is a pseudo UGen. BHiPass4 is built by cascading 2 SOS sections.

Class Methods

BHiPass4.ar(in, freq: 1200.0, rq: 1.0, mul: 1.0, add: 0.0)

Arguments:

in	input signal to be processed.
freq	cutoff frequency. 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.
