EQ, or parametric, filters can be designed on this tab (see
). Enter a gain, bandwidth, and a
center frequency (Fc). Either bandpass (positive gain) or band-reject (negative gain) filters can be created

Biquads are good at simulating analog filter designs. For each biquad section on this tab, enter the
desired analog filter type to simulate (Butterworth, Chebyshev, Inverse Chebyshev, Elliptic, or Bessel).
Parameter entry boxes appropriate to the filter type are shown (ripple, for example, with Chebyshev filters,
etc.). Enter the desired design parameters, and the response is shown (
