Select spectral ranges
When working in a spectral display, you can use the Marquee Selection, Lasso Selection, or Effects Paintbrush tool
to select audio data within specific spectral ranges. The Marquee Selection tool lets you select a rectangular area. The
Lasso Selection and Effects Paintbrush tools (available only in Spectral Frequency Display) let you make free-form
selections. All three tools allow for detailed editing and processing, including incredible flexibility in audio resto-
ration work. For example, if you find audio artifacts, you can select and edit just the affected frequencies, producing
superior results with faster processing.
The Effects Paintbrush tool creates unique selections that determine the intensity of applied effects. To adjust
intensity, either layer brush strokes or change the Opacity setting in the toolbar. The more opaque the white, selected
area is, the more intense applied effects will be.

• To move the selection, position the pointer in the selection, and drag it to the desired location.
• To resize the selection, position the pointer on the corner or edge of the selection, and drag it to the desired size.
(For paintbrush selections, you can also adjust the Brush Size setting in the toolbar.)
• To add to a lasso or paintbrush selection, Shift-drag. To subtract from the selection, Alt-drag.
• To determine the intensity of effects applied to paintbrush selections, adjust the Opacity setting in the toolbar.
• To select audio above and below marquee selections, select Exclude Selection in the toolbar. (For example, if you

same time range.)
By default, Adobe Audition plays all audio in the same time range as a spectral selection. To hear only the selection,
right-click the standard or circled Play button, and select Play Spectral Selection.
