amplitude scale is in dB and is adjustable between 3
and 24 dB using the vertical scale buttons
(Figure 11-10).
Adjusting filters in the display
To view a filter in the display, turn on the filter. The
shape of the filter, according to its current settings,
is shaded in the same color as the filter's knob(s).
Each filter has a handle, displayed as shown below
in Figure 11-12 (in the filter's color), for adjusting
its boost/cut and/or frequency:
Figure 11-12: Drag the filter handle to adjust its frequency and/or
boost/cut. Drag the Filter Q handles to adjust the Q.
For the EQ filters, when you click the handle, you'll
also see lines on either side for adjusting the Q
parameter, as shown above.
Filter display options
The Filter display options menu (Figure 11-10)
provides several options for the EQ filter display:

What it does
Turns off both the FFT and
Spectrogram in the Filter display.
Shows/hides a real time FFT analysis
of the current signal being EQ'd,
post EQ filter.
Shows/hides a real-time spectro-
gram "waterfall" in the background
of the filter display, post EQ filter.
Shows/hides the colored area below
EQ filter points.
Shows/hides the enlarged filter dis-
play in the CueMix FX window.
FFT display
Choose Show FFT from the Filter display options
menu (Figure 11-10) to superimpose a real-time
Fast Fourier Transform (FFT) frequency
measurement curve over the EQ filter display, as
demonstrated in Figure 11-13:
FFT curve
Figure 11-13: FFT display.
The FFT curve is post-filter. Therefore, the FFT
shows the results of the EQ filter(s) being applied.
Use the global EQ button for the input or output
channel (Figure 11-3 and Figure 11-6,
respectively) to toggle between the EQ'd and non-
EQ'd FFT display.
Spectrogram
Choose Show Spectrogram from the Filter display
options menu (Figure 11-10) to superimpose a
real-time spectrogram "waterfall" display in the
background of the EQ filter display, as
demonstrated in Figure 11-14:
Figure 11-14: FFT display.
The spectrogram scrolls from top to bottom, where
the top edge of the display represents what you are
hearing "now". Color represents amplitude along
