Adjusting filters in the display
Each filter has a handle, displayed as shown below 
in Figure 10-12 (in the filter’s color), for adjusting 
its boost/cut and/or frequency:
Figure 10-12: 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 10-10) 
provides several options for the EQ filter display:
FFT display
Choose Show FFT from the Filter display options 
menu (Figure 10-10) to superimpose a real-time 
Fast Fourier Transform (FFT) frequency 
measurement curve over the EQ filter display, as 
demonstrated in Figure 10-13:
Figure 10-13: 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 10-3 and Figure 10-6, 
respectively) to toggle between the EQ’d and non-
EQ’d FFT display.
Spectrogram
Choose Show Spectrogram from the Filter display 
options menu (Figure 10-10) to superimpose a 
real-time spectrogram “waterfall” display in the 
background of the EQ filter display, as 
demonstrated in Figure 10-14:
Figure 10-14: 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 
the left/right frequency spectrum. The amplitude 
color scale runs from black (silence) to red (full 
scale) as follows:

Menu option What it does
Show no analysis Turns off both the FFT and 
Spectrogram in the Filter display.
Show FFT Shows/hides a real time FFT analysis 
of the current signal being EQ’d, 
post EQ filter.
Show Spectrogram Shows/hides a real-time spectro-
gram “waterfall” in the background 
of the filter display, post EQ filter.
Show Band Response Shows/hides the colored area below 
EQ filter points.
