Use the matched EQ on a channel strip
Match EQ creates a filter curve based on the differences between the spectrum of the
template and the current material. This curve automatically compensates for differences
in gain between the template and the current material, with the resulting EQ curve
referenced to 0 dB. A yellow filter response curve, showing the average spectrum of
your mix, is visible in the main display when the EQ Curve button is active. This curve
approximates (mirrors) the average spectrum of your source audio file.
1. In Logic Pro, choose the channel strip that you want to match from the Sidechain
pop-up menu of the Match EQ window.
2. Click the Reference Learn button.
3. Play the entire source audio file from start to finish. To stop the learn process, click the
Reference Learn button again.
4. Return to the start of your mix, click the Current Learn button, and play your mix (the
current material) from start to finish.
5. When you are done, click the EQ Curve Match button.
Edit the Logic Pro Match EQ filter curve
You can edit the filter curve in the EQ Curve display by adjusting the various points shown
in each band. As you drag a point, the current value is shown, allowing precise changes.
Adjust Match EQ curve values
In Logic Pro, do any of the following:
• Drag horizontally to shift the peak frequency for the band (over the entire spectrum).
• Drag vertically to adjust the gain of the band.
• Hold down Shift, then drag vertically to adjust the Q Factor.
• While clicking, press Option to reset the gain to 0 dB.
• Press Option to reset all changes you have made to the curve.
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.
• In Logic Pro, drag either scale to set values of up to +20 dB and −100 dB.
Change Match EQ gain with the scales
• In Logic Pro, 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.
