Figure 26. Filter Dialog Box, Filter Not Bypassed
Above the graph, each filter has a "handle" (circled in red above) placed directly
above the cutoff or center frequency whose number corresponds to the filter number
(outlined in red). Clicking a handle or clicking the table row brings focus to that filter.
<Click+hold+dragging> the handle horizontally changes the cutoff or center frequency to
a new position on the x axis.
The table below shows each filter type with default parameter settings. The table
immediately following shows the possible range for each parameter.
