Spectral Gate
The Spectral Gate separates the signal above and below the Threshold level into two
independent frequency ranges—that you can modulate separately. It can produce
some unusual and rich filtering effects.
Spectral Gate Parameters
 Threshold slider and field: Sets the threshold level at which 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.
 Center Freq. (Frequency) knob and field: Sets the center frequency of the frequency
band to be processed by the Spectral Gate.
 Bandwidth knob and field: Sets the bandwidth of the frequency band to be
processed by the Spectral Gate.
 Low Level slider and field: Blends the frequencies of the original signal below the
selected frequency band with the processed signal.
 Super Energy knob and field: Controls the level of the frequency range above the
threshold.
 Sub Energy and field: Controls the level of the frequency range below the threshold.
 High Level slider and field: Blends the frequencies of the original signal above the
selected frequency band with the processed signal.
 Gain slider and field: Adjusts the amount of gain for the final output signal.
