Did you ever wonder how it would be if you could just grab that obvious peak in the frequency
spectrum analyzer? That's possible in Pro-Q! If the Post-EQ or Pre-EQ
analyzer is active, and you leave the mouse above the spectrum for a few seconds, Pro-Q will automatically enter Spectrum Grab mode. Existing EQ bands will be dimmed while the spectrum
freezes. You can now simply grab one of the peaks in the white output spectrum line, and drag to
adjust. The most important peaks in the signal will show a label with their frequency (or note value when the piano display is enabled).
After dragging a peak and releasing the mouse button, the interface will revert back to normal
again and you'll see the new EQ band that has just been added, so you can customize it if
By default, Spectrum Grab is enabled, but if you find it distracting, you can disable it in
the Analyzer Settings panel, accessible via the bottom bar.
You can also activate Permanent Spectrum Grab mode by clicking and holding in the
spectrum area until the highlight becomes blue. This freezes the spectrum permanently so you
can grab and drag multiple spectrum peaks. To exit this mode, simply click on the display
background instead of on the white spectrum curve.
Spectrum Grab works best when the Post-EQ setting is enabled in the Analyzer settings, because this relates best to what you are actually
hearing. Spectrum Grab will also work with only the Pre-EQ spectrum enabled, but when you grab
and adjust a peak by dragging it down, you won't see this reflected in the spectrum of
In Spectrum Grab mode, only Bell filters are created, and an appropriate Q is determined
automatically. Of course, after creating a new band, you can further customize it
using the normal band controls.
