The Biquad Filter Module implements a subtractive synthesis six-coefficient digital IIR filter with input/output power balancing for some pole stability. It takes an input signal and several continuous real-time parameter values and produces a filtered output Signal. Available forms of the filter include: Lowpass, Highpass, Bandpass, Notch, and Allpass. For more information about IIR filter forms and configurations, see Robert Bristow-Johnson's excellent EQ Cookbook.
For a key to understanding the tables on this page, see the Module Types page.
