While working on sound for a story, you may find that you want to edit a sound in a way that's easy in your favorite dedicated sound editor (like Goldwave, Audacity, Audition/Cool Edit, Soundbooth, etc.) but not in Springboard. Just for these situations, Springboard supports editing a sound clip in an external program. You can use the features you're used to in your sound editor while still benefiting from Springboard's storyboard structure.
The steps in the process are:
Sound Clips And Split Files
When you are done editing a sound clip externally, you can choose Edit > Unify to merge your sound back into the main story file if you like. Unlike editing images externally, you don't have to do this - you can keep sound files split out if you like.
Also, unlike other split files, which are saved as Springboard story files (.sbd), split files containing sound clips are saved as Windows WAVE files (.wav). This allows them to be edited by any standard sound editing program.
