Edit the Match EQ lter curve
You can edit the lter curve in the graphic display by adjusting the various points shown in each
band. As you drag a point, the current value appears in a small box inside the graphic display,
allowing precise changes.
Adjust Match EQ curve values
Do any of the following:
m To shift the peak frequency for the band (over the entire spectrum), drag horizontally.
m To adjust the gain of the band, drag vertically.
m To adjust the Q Factor, Shift-drag vertically.
m To reset the gain to 0 dB, Option-drag.
Note: If you manually modify the lter curve, you can restore it to the original (or at) curve by
Option-clicking the background of the Analyzer display. Option-click the background again to
restore the most recent curve.
The Q factor of the lter is determined (and set) by the vertical distance between the clicked
position and the curve.
Set the Q factor in Match EQ
Do either of the following:
m To set the maximum Q value of 10 (for notch-like lters), click the curve.
m To decrease the Q value, click above or below the curve. The farther you click from the curve, the
smaller the value (down to the minimum of 0.3).
Change the Match EQ scale range
The colors and modes of the dB scales on the left and right of the display are automatically
adapted to the active function. If the Analyzer is active, the left scale displays the average
spectrum in the signal, while the right scale serves as a reference for the peak values of the
Analyzer. A dynamic range of 60 dB is shown by default. If this is not precise enough for your
edits, you can increase the range.
m Drag either scale to set values of up to +20 dB and −100 dB.
Change Match EQ gain with the scales
m Drag either scale to adjust the overall gain of the lter curve from −30 to +30 dB.
The left scale—and the right, if the Analyzer is inactive—shows the dB values for the lter curve.
