BHiPass4 : Object

24db/oct rolloff - 4th order resonant Hi Pass Filter [1]
Source: BEQSuite.sc

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.

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.

mul
