Single Band EQs
Following are descriptions of each of the effects found in the Single Band submenu.
High Cut and Low Cut Filter
As their names suggest, the Low Cut Filter attenuates the frequency range below the
selected frequency, while the High Cut Filter attenuates the frequency range above the
selected frequency. Each has a single parameter letting you set the cutoff frequency.
High Pass and Low Pass Filter
The High Pass Filter affects the frequency range below the set frequency. Higher
frequencies pass through the filter. You can use the High Pass Filter to eliminate the
bass below a selectable frequency. In contrast, the Low Pass Filter affects the frequency
range above the selected frequency. Both filter plug-ins offer the following parameters:
 Frequency field and slider: Sets the cutoff frequency.
 Order field and slider: Sets the filter order.
 Smoothing field and slider: Adjusts the amount of smoothing (in milliseconds).
High Shelving and Low Shelving EQ
The Low Shelving EQ affects only the frequency range below the selected frequency,
while the High Shelving EQ affects only the frequency range above the selected
frequency. Each has parameters for Gain, which you use to boost or cut the level of the
selected frequency band, and Frequency, which you use to set the cutoff frequency.
Parametric EQ
The Parametric EQ is a simple filter with a variable center frequency. It can be used to
boost or cut any frequency band in the audio spectrum, either with a wide frequency
range, or as a notch filter with a very narrow range. A symmetrical frequency range on
either side of the center frequency is boosted or cut. The Parametric EQ offers the
following parameters:
 Gain field and slider: Sets the amount of gain.
 Frequency field and slider: Sets the cutoff frequency.
 Q-Factor field and slider: Adjusts the Q (bandwidth).
