Repairing audio
Sound Forge provides several ways to repair audio glitches.
Copying the other channel
For glitches in a single channel of a stereo file, Sound Forge can replace the glitched section of damaged
channel with the corresponding data from the “good” channel.
Note:
This method only works if both channels contain
similar audio.
1.
Open the stereo file containing the glitch.
2.
Create a selection in the channel containing the glitch, three or four times longer (maximum 50 ms) than
the glitch itself.
3.
From the Tools menu, choose Repair, and choose Copy Other Channel from the submenu. Sound Forge
replaces the selected data with the corresponding data from the “good” channel. In addition, Sound Forge
creates rapid crossfades at the beginning and end of the replacement selection to prevent a new glitch
from being created.
Tip:
If this method fails to repair the glitch, undo it and apply
Copy Other Channel again, this time using a longer selection.
Damaged data in the right channel is
replaced with data from the left channel
