Digital Processing 145
3. Parametric Equalizer
Parametric EQ allows you adjust the individual parameters of the filter.
Boost and Cut controls “how much” of the signal will be boosted or cut.
Center Frequency sets the center frequency to be boosted or cut, and the
Bandwidth control sets the width of the band to be boosted or cut. The
three parameters are diagrammed below.
The parametric equalizer is a digital (non real-time) equivalent of an
analog equalizer with +12 db of boost and a whopping -48 dB of cut.
Accurate center frequency and bandwidth controls are precise and
exceptionally wide range.

The display will show the current points of the sample to be equalized,
which will be the start and end points of the current sample. Select the
section of sample to be EQ'ed, then press ENTER.
✱
Tip:
The left and right cursor buttons
will change the start and end points so that
they fall on positive zero-crossing points in
the waveform. This will minimize clicks in
the sound when processing only part of a
sample.
