Graphic Equalizer
The graphic equalizer offers 31 standard ISO
center frequency controls with constant Q or
proportional Q filters, as well as adjustable filter
bandwidth.
GEQ Parameters :
Faders : Graphic representation of the 31 EQ
filter controls. Adjust faders one at a time, or
drag across any region of the graph to adjust
faders.
To return all GEQ faders to their "0" setting,
click or tap the "Flatten" button in the upper left
corner of the graphic display.
Filter Type : This selects proportional Q or
constant Q (default) filters.
• Constant Q filters have consistent Q/
bandwidth regardless of the amount of
boost or cut.
• Proportional Q filters get narrower with
increasing boost/cut.
Differences in filter shapes can be observed on
the frequency response display.
Bandwidth : This sets the bandwidth of all
GEQ filters to the same value within a range of
1/4 octave to 1/2 octave (before proportional
adjustment). The default bandwidth is 1/3
octave.
High-Pass Filter
A high-pass filter (HPF) is a single ended filter
without a level control, passing only signal
above the selected corner frequency. Filter
types include Bessel, Butterworth, Linkwitz,
and Linkwitz Notch, including a variety of filter
slopes.
HPF Parameters : filter type, frequency
Low-Pass Filter
A low-pass filter (LPF) is a single ended filter
without a level control, passing only signal
below the selected corner frequency. Filter
types include Bessel, Butterworth, Linkwitz,
and Linkwitz Notch, including a variety of filter
slopes.
