A low shelf equalizer UGen. 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.
- Value Params
- freq
cutoff frequency.
- gain
boost/cut at the cutoff frequency (in decibels).
- in
input signal to be processed.
- rs
the reciprocal of the slope 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/sample-rate andgain
