Expand description
State Variable Filter with simultaneous lowpass, highpass, bandpass, notch, and peak outputs.
Unlike a biquad, the cutoff and resonance can be swept every sample without recomputing a
coefficient set, and all five responses are available from a single process
call. Ported from Andrew Simper’s “Double Sampled, Stable State Variable Filter”
(musicdsp.org), which internally runs two half-rate passes per sample for stability at high
cutoff/resonance settings.
