Editing, Repairing,
and Synthesizing
Audio
This chapter introduces some of Sound Forge’s advanced editing, repair, and synthesis features.
Crossfading, overwriting, and replicating
Earlier in this manual, paste and mix were described as ways of adding clipboard contents to the current data
window. As your audio editing projects become more elaborate, you may discover the need for three more
sophisticated paste operations: crossfade, overwrite, and replicate.
Crossfading
Crossfading is a variation on pasting that joins two selections of audio data that would be awkward or
distracting if pasted together. In crossfading, the destination data decreases in volume (fades out) as the
source data increases in volume (fades in). A crossfade is the audio equivalent of the filmmaker’s dissolve.
1.
Open the Voiceover.pca and Musicbed.pca files.
2.
Select all data in the Voiceover data window.
3.
Copy the selection. The data is placed on the clipboard.
4.
Place the cursor at the approximate middle of the Musicbed data window. This is where the crossfade will
begin.
5.
From the Edit menu, choose Paste Special, and choose Crossfade from the submenu. The Crossfade dialog
appears.
You can also display the Crossfade dialog by right-clicking the data window and choosing
Crossfade or by pressing .
6.
From the Preset drop-down list, choose Normal crossfade and click OK.
7.
Play the Musicbed.pca file. Notice that the volume of the musicbed decreases while the voiceover volume
increases.
Overwriting
Overwriting allows you to replace the current selection with the contents of the clipboard. Sound Forge
overwrites with two basic guidelines:
• If the selection is longer than the clipboard contents, data is overwritten from the beginning of the
selection for the length of the clipboard contents only. The remainder of the selection remains in the data
window.
• If the clipboard contents are equal to or longer than the selection, data is overwritten for the length of the
selection only.
