BBandStop | SuperCollider 3.9.3 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.

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
