Basic operation for Cool Edit Pro LE
Editing
Cool Edit Pro LE makes it easy for you to perform waveform editing. Here’s
the basic procedure for waveform editing.
■ Select the region that you wish to edit
First select the region that you wish to edit.
In Cool Edit Pro LE, the waveform can be selected in a variety of ways. By
combining the following methods, you can quickly and easily select the
desired waveform.
• Drag the mouse to left or right to select a region
fig.4-11.eps_30
• Right-click to extend the selected region
• Use the left/right arrow keys to change the starting point of the
selected region
• Hold down the Shift key and use the left/right arrow keys to change
the end point of the selected region
• Double-click the waveform to select the entire displayed area
• Input values in the Selection field to specify the selected region
In addition, you can use the Zero Crossings function to move the starting
point and end point of the selected region to the nearest location with an
amplitude of zero. If you use this function, you can insert or delete portions
of the waveform without causing an abrupt volume change where the
waveform was joined, and thereby avoid causing noise at the location where
waveform data was cut or pasted.
To activate the Zero Crossings function, select Zero Crossings – Adjust
Selection Inward from the Edit menu, or click in the toolbar.
