Working with Filters
When you initially open the parameter window of a parametric EQ, there are no peak/notch filters in
the response plotter. Add filter points as you need them, up to the maximum number available for the
selected processor block.
To add a new filter point:
1. Click the [New] button.
2. A filter point appears at 0dB with a default frequency value
of 1kHz and a bandwidth of 2/3 octave.
To remove all filter points:
1. Click the [Clear] button or select [Edit>Clear Filters] from the
parameter window menu bar.
2. The Clear Options dialog appears, as pictured to the right in
figure 48.
3. Select [Clear All Filters] and click [OK]. This removes all filter points from the response plotter and
returns the cut/shelf filters to the default settings.
To remove specific filter points:
4. Click on a filter point to select it, or C
TRL+Click to select multiple filters.
5. Press the D
ELETE key – OR – Click the [Clear] button to open the Clear Options dialog and select
the [Clear One Filter] option, which also applies to a multiple filter selection.
Note: You cannot remove cut/shelf filter handles, however you can return them to
their default settings by using [Clear] or DELETE.
Adjusting Filters in the Response Plotter
You can change filter settings by dragging the filter points and handles with the mouse.
To adjust gain and frequency:
1. Position the cursor over the center of the filter point or handle.
2. The cursor changes to the move symbol:
3. Click and drag the filter left or right to adjust frequency, and up or down to adjust gain.
Note: The response plotter displays a curve only for the selected filter. The
combined curve is displayed in the response graph.
To adjust filter point bandwidth:
1. Position the cursor over either of the filter’s bandwidth control points.
2. The cursor changes to the horizontal resize symbol:
3. Click and drag the control point left or right to set the bandwidth.
