Match EQ
Logic Pro Match EQ overview
Match EQ allows you to analyze and store the average frequency spectrum of an audio
file as a template. You can apply this template to another audio signal so that it matches
the spectrum of the original file. This is also known as a fingerprint EQ, where one sonic
fingerprint is applied to another signal.
Match EQ lets you acoustically match the tonal quality or overall sound of different
songs you plan to include on an album, for example, or to impart the color of any
source recording to your own projects.
Match EQ is a learning equalizer that analyzes the frequency spectrum of an audio signal
such as an audio file, a channel strip input signal, or a template. The average frequency
spectrum of the source file (the template) and of the current material (this can be the
entire project or individual channel strips within it) is analyzed. These two spectra are
then matched, creating a filter curve. This filter curve adapts the frequency response of
the current material to match that of the template. Before applying the filter curve, you
can modify it by boosting or cutting any number of frequencies or by inverting the curve.
The Analyzer allows you to visually compare the frequency spectrum of the source file
and the resulting curve, making it easier to make manual corrections at specific points
within the spectrum.
Note:
Although Match EQ acoustically matches the frequency curve of two audio signals,
it does not match any dynamic differences between the two signals.

Logic Pro Match EQ parameters
Match EQ offers the parameters described in this section.
Match EQ parameters
• Fade Extremes checkbox: Select to set an automatic high cut and low cut threshold.
Matching signals above or below these thresholds are slowly faded to zero.
• Main display: Displays the filter curve created by matching the template to the current
material. You can also edit the filter curve directly (see Edit the Logic Pro
Match EQ
filter curve).
