Editing a Waveform

Waveforms can be edited in multiple ways. Individual segments may be selected and edited, or parts of the waveform may be cut, copied, pasted or cleared from the screen.

Selecting Parts of a Waveform

To select a part or segment of a waveform, click the Edit Select icon. Use the cursor to highlight the area for editing or math operations.

When a portion of a waveform is selected and highlighted, the Status Bar reflects the start and end points of the highlighted area and the total number of points selected. The highlighted area can be adjusted using the arrow keys:

∙Right arrow - selects the right side of the highlighted area

∙Left arrow - selects the left side of the highlighted area

∙Up arrow - increases the highlighted area

∙Down arrow - decreases the highlighted area

In normal viewing mode, the up and down arrow keys may not seem to increase or decrease the highlighted area in the waveform edit window. However, the Status Bar will indicate the change and zooming will show the effect more efficiently.

To invalidate a highlighted selection, click past the end of the waveform or click the Edit Select icon.
