Viewing the Filter in FVTool

This section teaches you how to use the Filter Visualization Tool (FVTool) to view the

octave-band filter. It also describes how to annotate your filter.

Click the Filter Manager button to display the Filter Manager, which lists your

saved filters.

Press Ctrl+click on each filter name to select all the filters, and then click FVTool.

FVTool opens with the filter responses overlaid for easy comparison. (If you want to

view a single filter in FVTool, click the Full View Analysis button when that filter

is shown in the FDATool display panel or select View > Filter Visualization Tool).
