of its frequency band to any value between
0dB and -40 dB in 1dB steps.
Center Frequency:
Note that the Center Frequency of each
band is labelled underneath each slider, and
that bands are more closely spaced at low
frequencies.
Gain Indication:
Above each slider control, the gain for that
frequency band is given. The gain can also
be visualized graphically by the position of
the slider control.
Normalize Button:
This button instantly shifts all slider controls
up together until the top slider is at 0dB.
After normalization, the relative positioning of
the sliders remains the same. This allows
the digital equalizer to implement the desired
equalization curve with minimum signal loss.
