AudioShake supports sync licensing by producing clean instrumental and vocal stems from fully mixed recordings, making catalog tracks available for sync even when original session files no longer exist. Sync licensing requires instrumental versions, clean vocal tracks, and often individual instrument stems for music supervisors to evaluate and edit. AudioShake extracts all of these from the finished master, opening catalog recordings to sync opportunities that would otherwise be blocked by the absence of original multitracks. Legacy and archival material can be licensed for sync without returning to the original production.
