Equalizer
The Octopus’ (Parametric) Equalizer effect can be used to accentuate or
remove selected parts of the signal's spectrum. The effect features four
separate bands. Each band has controls for Frequency, G (Gain) and Q
(Quality).
The Frequency control is used to set the centre frequency at which the filter
band operates. To set the centre frequency click on the numerical display
and drag the mouse up or down. The available range is 30 Hz to 20,267 Hz.
The G (Gain) control is used to set the gain of the selected frequency band.
When the control is set to the middle position no gain is applied to the
frequency band. If the control is turned left then the signal will be cut. The
closer the control to the leftmost setting the more the signal will be cut. If
the control is turned right then the signal will be boosted. The closer the
control is set to rightmost the more the signal will be boosted. The range is
-24dB...0dB...+24dB.
The Q or Quality control is used to set the width of the band that is cut or
boosted. Increasing the value of the Q control makes the band affected by
the filter narrower and therefore, more pronounced.
