High Shelf Filter

EQ1 High Shelf

f:11039 S:1.5 Gn: +4

The High Shelf filter can be thought of as the world’s most flexible version

of the venerable “Treble” tone control familiar to users of radios, home

stereos and boom boxes.

The High Shelf filter boosts or cuts all frequencies above cutoff frequency

“f” by the Gain (“Gn”) amount (in dB). Additionally, you can vary the

slope (“S”) of the shelf from 2dB/octave (S=0.3) to 12dB/octave (S=2.0).

Peaking Filter

EQ1 Peaking

f: 884 Q:2.4 Gn:-10

This is the traditional fully parametric EQ. The filter boosts or cuts the

signal at frequency “f” by the Gain (“Gn”) amount (in dB). Additionally,

you can vary the bandwidth of the peak or dip with the “Q” control

(higher Q = narrower bandwidth).

Notch Filter

EQ1 Notch

f: 3775 Q:5.8

The Notch Filter passes all frequencies except for a band centered around

frequency “f,” which is sharply attenuated. The setting of the “Q” control

determines the width of the notch (higher Q = narrower notch).

Band Pass Filter
