You can set the upper and lower limits of the range independently by dragging the left
and right handles of the slider bracket. You can move the entire range by dragging the
center section of the slider bracket.
Spectral Gate
The Spectral Gate is an unusual filter effect that can be used as a tool for creative sound
design.
It works by dividing the incoming signal into two frequency ranges—above and below
a central frequency band that you specify with the Center Freq and Bandwidth parameters.
The signal ranges above and below the defined band can be individually processed with
the Low Level and High Level parameters and the Super Energy and Sub Energy
parameters. See Using the Spectral Gate.
Spectral Gate Parameters
The Spectral Gate panel includes the following parameters:
Gain slider
Sub Energy and Low
Level controls
Center Freq. and
Bandwidth knobs
Speed, CF Modulation,
and BW Modulation
sliders Graphic display
Super Energy and High
Level controls
Threshold slider
• Threshold slider and field: Sets the threshold level for division of frequency ranges. When
the threshold is exceeded, the frequency band defined by the Center Freq. and
Bandwidth parameters is divided into upper and lower frequency ranges.
• Speed slider and field: Sets the modulation frequency for the defined frequency band.
• CF (Center Frequency) Modulation slider and field: Sets the intensity of center frequency
modulation.
• BW (Band Width) Modulation slider and field: Sets the amount of bandwidth modulation.
• Graphic display: Shows the frequency band defined by the Center Freq. and Bandwidth
parameters.
