Filter Parameters
These four fields (on the right side of the page) control the parameters that can also be
adjusted in the graph.
Filter number — Selects a filter to display on the graph or copy and paste functionality.
•
• Frequency — Adjusts the center frequency of the filter.
Boost/Cut — Adjusts the amount of amplification or attenuation applied to that specific
•
filter.
• Q — Adjusts the bandwidth to where the boost or cut is applied. As the Q value
increases, the bandwidth becomes narrower.
NOTE: When values are altered in the filter parameter fields, the graphic display is
updated to reflect the changes.
Modifying Filter Parameters
The graph in the Filter dialog box displays a graphical representation of the selected and
composite filters.
• An orange line indicates the composite curve of all active filters.
• A blue line indicates the selected filter.
• Inactive filters do not contribute to the orange composite curve. However, when
selected, an inactive filter appears as a dotted line independent of the composite curve.

In the Filter dialog box, select the filter to be modified. To do so, either click the filter
1.
