Figure 19. Shelf Filters
To use these filters, enter the gain desired and the corner frequency. Choose the mode to use (
Bass
or
Treble
); the response is plotted on the
Effect Filter Response
graph.

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

Analog Simulation Filters
Biquads are quite 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,
and so forth). Enter the desired design parameters and the response is shown. The
Analog Simulation
Filters
tab is shown in
