Figure 9. Filter Dialog Box, Filters Added

Within the dialog box, a filter is focused when a filter type is inserted, or is focused by clicking the filter number to the left of the filter selection drop-down list. Note how filter 3 in the figure below is highlighted in yellow, indicating it is the filter in focus. The results of the filter in focus (independent of other filters) shows in the graph as a dotted line of the same color as its filter row when bypassed. When active (not bypassed), the line is solid.

Figure 10. Filter Dialog Box, Filter Not Bypassed

When multiple filters are enabled, the graph indicates the focused filter result (independent of other filters) in the color of the filter row in the type/parameters table. The composite response of all filters is displayed in red.

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.
