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.
BLowPass.ar(in, freq: 1200.0, rq: 1.0, mul: 1.0, add: 0.0)
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 | |
| add | |
BLowPass.sc(dummy, freq: 1200.0, rq: 1.0)
calculate filter coefficients.
