Swap Channels

The Swap Channels command allows you to exchange the right and left channels if you are working with a stereo recording.

Important: This option is only available in Screenblast Sound Forge. If you're using the full version of Sound Forge, use the Channel Converter.

Time Stretch

If you are working with the full version of Sound Forge, choosing Time Stretch from the Process menu starts Sony Pictures Digital’s XFX Time Stretch plug-in. For more information on using the XFX Time Stretch plug-in, refer to Sound Forge online help (from the Help menu, choose Contents and Index).

If you are using Screenblast Sound Forge, choosing Time Compress/Expand from the Process menu starts the ExpressFX Time Stretch plug-in. This tool allows you to adjust the length of an audio file using a single control, the Final length slider. For more information on using the ExpressFX Time Stretch plug-in, click the Help button in the Time Stretch dialog.
