The red curve above is an in-room measured curve, and the green curve is a generated EQ frd file (loaded as an
and offset 60dB for display).
To obtain parametric equalizer settings, put a check in the box labeled "show parametric EQ filters" and the
form will expand to show:
Six sets of EQ section controls appear. Each section can be set to PEQ (parametric equalizer), High Shelf, or
Low Shelf, and can be set for manual mode, bypass, or automatic mode. You can select the effective frequency,
the "Q" (the ratio of center frequency to bandwidth), and the dB intensity of each. The result of applying all the
filters will appear as a gold curve on the graph.
For example, for each of 6 sections, you can apply a parametric filter to cut or boost a selected amound (in dB), at
a selected frequency, and with a selected "Q". Q is related to bandwidth. A lower-Q setting means that the boost
or cut will be effective over a wider range of frequencies, while a higher-Q setting will cause the effect to act over
a narrower range of frequencies with a sharper curve.
