The filter curve is updated automatically each time a new Reference or Current material
spectrum is learned or loaded when the EQ Curve Match button is turned on. You can
alternate between the matched (and possibly scaled or manually modified) filter curve
and a flat response by turning the Match button on or off.
Match the EQ of a project mix to the EQ of a source audio file
1. In Logic Pro, in the project you want to match to the source audio file, insert Match EQ
(typically on Output 1-2).
2. Drag the source audio file to the Reference Learn button.
3. Return to the start of your mix, click the Current Learn button, and play your mix
(the current material) from start to finish.
4. When you are done, click the EQ Curve Match button.
When you click either of the Learn buttons, the main display shows the frequency curve for
the function. You can review any of the frequency curves when no file is being processed
by choosing one of the other view options or modes.
Note: Only one of the Learn buttons can be turned on at a time. For example, if the
Reference Learn button is on and you click the Current Learn button, analysis of the
(Reference) template file stops, the current status is used as the spectral template,
and analysis of the incoming audio signal (Current Material) begins.
Edit spectra with the Match EQ Action menu
This menu provides commands that can be applied to the either the Reference or the
Current Material spectrum.
• In Logic Pro, choose one of the following from the Action menu:
• Clear Current Material/Reference Spectrum: Clears the current spectrum.
• Copy Current/Reference Spectrum: Copies the current spectrum to the Clipboard
(this can be used by any Match EQ instance in the current project).
• Paste Current/Reference Spectrum: Pastes the Clipboard contents to the current
Match EQ instance.
• Load Current Material/Reference Spectrum from setting file: Loads the spectrum
from a stored setting file.
• Generate Current Material/Reference Spectrum from audio file: Generates a
frequency spectrum for an audio file you have chosen.
Refine the Match EQ curve
Each time you match two audio signals, either by loading or learning a new spectrum
while Match is activated or by turning on Match after a new spectrum has been loaded,
any existing changes to the filter curve are discarded and Apply is set to 100%.
In Logic Pro, do either of the following:
• Drag the Apply slider down from the default 100% value to avoid extreme spectral
changes to your mix.
• Drag the Smoothing slider to adjust the spectral detail of the generated EQ curve—
if required.
