5.5.8 Notch

Band Elimination Filter (Notch)
Notch is a band rejection filter with resonance. Band Reject filters work in the opposite fashion
as bandpass filters: they only weaken frequencies within a particular frequency range, defined
by two cutoff frequencies on both sides (or by a middle frequency and a bandwidth). Higher
and lower frequencies can pass through unhindered.
Main Panel
The Notch Filter has the following parameters:
•
Frequency control and Frequency menu: The Frequency control allows you to set the
middle frequency in semitones (Trans) or in Hertz (Hz), upon the selection in the nearby
Frequency menu.
•
Resonance control: This control (labeled Res) allows you to adjust the resonance of the
filter.
•
B-width control: Sets the bandwidth of the filter around the middle frequency. Its values
is measured in octaves.
