BLowShelf | SuperCollider 3.13.0 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

BLowShelf.ar(in, freq: 1200.0, rs: 1.0, db: 0.0, mul: 1.0, add: 0.0)

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!
rs	the reciprocal of S. Shell boost/cut slope. When S = 1, the shelf slope is as steep as it can be and remain monotonically increasing or decreasing gain with frequency. The shelf slope, in dB/octave, remains proportional to S for all other values for a fixed `freq/SampleRate.ir` and `db`.
db	gain. boost/cut the center frequency in dBs.
mul
