Using the Spectral Gate
Using the Center Freq. and Bandwidth parameters, set the frequency band you want to
process using the Spectral Gate. The graphic display visually indicates the band defined
by these two parameters.
Once the frequency band is defined, use the Threshold parameter to set the level
above and below which the frequency band is divided into upper and lower ranges.
Use the Super Energy knob to control the level of the frequencies above the Threshold,
and use the Sub Energy knob to control the level of the frequencies below the
Threshold.
You can also mix the frequencies from the original signal outside the frequency band
defined by the Center Freq. and Bandwidth with the processed signal. Use the Low
Level slider to blend the bass frequencies below the defined frequency band with the
processed signal, and use the High Level slider to blend in frequencies above the
defined frequency band.
You can modulate the defined frequency band using the Speed, CF Modulation, and
BW Modulation parameters. Speed determines the modulation frequency, CF (Center
Frequency) Modulation defines the intensity of the center frequency modulation, and
BW (Band Width) Modulation controls the bandwidth modulation.
After making your adjustments, you can use the Gain slider to adjust the final output
level of the processed signal.
One way to get better acquainted with the operation of the Spectral Gate would be to
start with a drum loop. Set the Center Freq. to its minimum (20 Hz) and the Bandwidth
to its maximum (20000 Hz) value (so that the entire frequency range is processed). Turn
up the Super Energy and Sub Energy knobs, one at a time, then try different Threshold
settings. This should give you a good sense of how different Threshold levels affect the
sound of Super Energy and Sub Energy. When you come across a sound that you like or
consider useful, narrow the Bandwidth drastically, gradually increase the Center Freq.,
and then use the Low Level and High Level sliders to mix in some treble and bass from
the original signal. At lower Speed settings, turn up the CF Mod. or BW Mod. knobs.
