As soon as the Analyzer is activated, you can change the scaling with the Analyzer Top
parameter, on the right side of the graphic display. The visible area represents a dynamic
range of 60 dB. Drag vertically to set the maximum value to anywhere between +20 dB
and −40 dB. The Analyzer display is always dB-linear.
Note: When choosing a resolution, be aware that higher resolutions require significantly
more processing power. High resolution is necessary when trying to obtain accurate
analysis of very low bass frequencies, for example. It is recommended that you disable
the Analyzer or close the Linear Phase EQ window after setting the appropriate
EQ parameters. This will free up CPU resources for other tasks.
Match EQ
The Match EQ allows you to store the average frequency spectrum of an audio file as a
template and apply the 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.
The Match EQ enables you to 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.
You can use the Match EQ in different ways, depending on your intended outcome and
the audio you’re working with. In general, you will want to make your mix sound similar
to an existing recording—either your own or that of another artist.
Note: Although the Match EQ acoustically matches the frequency curve of two audio
signals, it does not match any dynamic differences between the two signals.
