EQ (AudioSuite)
EQ plug-ins provide a set of high-quality options for adjusting the frequency spectrum of audio
material:
• 1-Band EQ III
• 4-Band EQ III
• 7-Band EQ III
1-Band EQ III Parameters
The following table lists the 1-Band EQ III plug-in parameters.
Parameter Description
Input Sets the input gain of the plug-in before EQ processing, letting you make up gain or prevent
clipping at the plug-in input stage.
Input Polarity
control
Inverts the phase (polarity) of the input signal, to help compensate for phase anomalies
occurring in multi-microphone environments, or because of mis-wired balanced connections.
Type Lets you select an EQ type (High-Pass, Notch, High-Shelf, Low-Shelf, Peak, or Low-Pass).
The name of the type you select appears in the text field.
Filter
Q (Peak and Notch) Controls the width of the EQ band. Higher values represent narrower
bandwidths. Lower values represent wider bandwidths.
(High-Shelf and Low-Shelf) Changes the Q of the shelving filter. Higher Q values represent
steeper shelving curves. Lower Q values represent broader shelving curves.
(High-Pass and Low-Pass) Lets you select from any of the following Slope values: 6 dB,
12 dB, 18 dB, or 24 dB per octave.
Freq Lets you set the center frequency (Peak, High-Shelf, Low-Shelf, and Notch) or the cutoff
frequency (High-Pass and Low-Pass).
Gain Lets you control the amount that the selected frequencies are cut or boosted (for High-Shelf,
Low-Shelf, and Peak only).
Frequency Graph
Display
Shows a control dot that indicates the center frequency or cutoff frequency for the currently
selected filter type, and a frequency response curve. You can adjust the parameters by
dragging the control dot.
