Band reject filter
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.

Class Methods

BBandStop.ar(in, freq: 1200, bw: 1, mul: 1, add: 0)

Arguments:

in

input signal to be processed.

freq

center frequency. WARNING: due to the nature of its implementation frequency values close to 0 may cause glitches and/or extremely loud audio artifacts!

bw

the bandwidth in octaves between -3 dB frequencies.

mul
add
