You can edit the filter 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.
Do any of the following:
To shift the peak frequency for the band (over the entire spectrum), drag horizontally.
To adjust the gain of the band, drag vertically.
To adjust the Q Factor, Shift-drag vertically.
To reset the gain to 0 dB, Option-drag.
Note: If you manually modify the filter curve, you can restore it to the original (or flat) 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 filter is determined (and set) by the vertical distance between the clicked position and the curve.
Do either of the following:
To set the maximum Q value of 10 (for notch-like filters), click the curve.
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).
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.
Drag either scale to set values of up to +20 dB and −100 dB.
Drag either scale to adjust the overall gain of the filter curve from −30 to +30 dB.
The left scale—and the right, if the Analyzer is inactive—shows the dB values for the filter curve.
