The Dialogue Bar contains information about the currently
selected slider widget, group delay of the filter and the number
of channels controlled by the canvass. If no widget is selected,
the data boxes are blank.
An EQ canvass is the two dimensional area upon which EQ
slider widgets are placed. Slider widgets are graphical
representations of the sliders used in traditional graphic
equalisers. The bottom of the canvass is graduated in Hz
(cycles per second) and represents the frequency range. The
left side of the canvass is graduated in dB (decibels) and
represents the cut/boost range. The EQ canvass may be split to
show a view of the phase and group delay of an EQ curve.

used.
The Equalisation Curve is a graphic representation of the
desired frequency response of the equaliser. This line is
