| Parameter | Purpose |
|---|
| "Lower" slider | Sets the lower limit for
the center-frequency of the sweeping notch (within the allowable range extending from
0 up to the Nyquist frequency (i.e. half the sample rate)). |
| "Upper" slider | Sets the upper limit for
the center-frequency of the sweeping notch (within the allowable range extending from
the lower limit up to the Nyquist frequency). |
| "Rate" slider | Sets the rate (in Hz) at
which the notch center-frequency sweeps through its
profile from the lower limit to the upper limit. The sweep
follows an exponential rise from the lower limit to the upper limit,
followed by an exponential decay from the upper limit to the lower limit. |
| "Skew" slider | Adjusts the time-asymmetry
of the shape of the exponential frequency sweep. A value of 0.5 corresponds to a symmetric profile
(i.e. the rise profile
is a mirror image of the decay profile). |
| "Width" slider | Adjusts the
bandwidth of the notch as a fraction of the instantaneous center-frequency. As the center-frequency
sweeps through
its exponential profile, the bandwidth thereby adjusts accordingly. |
| "Depth" slider | Adjusts the
depth of the notch filter. Maximum depth (lower limit of slider) implies a deep notch; minimum depth (upper limit
of slider) implies a shallow notch. The depth is fixed in time.
|
| "Mix" slider | Adjusts the relative amplitudes
of the processed ("wet") and raw ("dry") signals. A value of 0.5 corresponds to an equal mix;
a value of 1 corresponds to maximum effect; and a value of 0 corresponds to no effect.
|
| "Output" slider | Adjusts the amplitude of the output signal. |
