Chapter 7 Working in the Waveform Editor 159
Graphically Editing Audio Files
The Waveform Editor includes four waveform editing tools you can use to graphically
edit the audio file in the waveform display.
Selection Tool
You can use the Selection tool to select part of an audio file, as described in “ Selecting
Part of an Audio File ” on page 154. When you open the Waveform Editor, the pointer is
a selection pointer (arrow). When you are done using another waveform editing tool,
you can return the pointer to a selection pointer by clicking the Selection Tool button.
Sample Edit Tool
You can graphically edit samples in the audio file using the Sample Edit tool. To use the
Sample Edit tool, the waveform display must be zoomed in enough to see individual
samples, which appear as small squares connected by a thin line.
To edit samples using the Sample Edit tool:
1 Click the Sample Edit Tool button above the time display.
The pointer becomes a Sample Edit pointer.
2 Zoom in on the part of the waveform you want to edit.
3 To graphically edit samples, do one of the following:
 Drag a sample up or down to a new value.
 Click directly above or below a sample.
 Drag left or right to reshape the waveform.
You can also edit samples numerically in the waveform display.
To edit samples numerically:
1 Control-click a sample, then choose Set Value from the shortcut menu.
2 In the sheet that appears, type a new value for the sample.
3 Click OK.
