 Low cut (cuts frequencies below the specied frequency);
 Low shelf (boosts or cuts frequencies lower than the specied frequency);
 Bell curve (boosts or cuts over a range of frequencies);
 Notch (sharply cuts frequencies within a narrow range);
 High shelf (boosts or cuts frequencies higher than the specied frequency);
 High cut (cuts frequencies above the specied frequency).
Each lter band can be turned on or off independently. Turn off bands that are not in use
to save CPU power.
To edit the lter curve, click and drag on the lter dots in the display. Horizontal movement
changes the lter frequency, while vertical movement adjusts the lter band's gain. To adjust
the lter Q (also called resonance or bandwidth), hold down the
Alt
(PC) /
Alt
(Mac)
modier while dragging the mouse. Note that the gain cannot be adjusted for the low cut,
notch and high cut lters. In these modes, vertical dragging adjusts the lter Q.
You can also use the numbered lter selector buttons to select a band for editing, and then
edit parameter values with the Freq, Gain and Q dials (and/or type values into the number
elds below each dial).
To achieve really drastic ltering effects, assign the same parameters to two or more lters.
As boosting will increase levels and cutting will decrease levels, use the global Gain eld to
optimize the output level for maximum level consistent with minimum distortion.
The Scale eld will attenuate the gain of all lters that support gain (all except low cut, notch
and high cut).
Enabling Hi-Quality mode via the (PC) /
Ctrl
(Mac) context menu can improve the
sound quality, particularly with low frequency signals or when working at high sample rates.
There is a slight increase in CPU usage in Hi-Quality mode.
