It’s always a struggle to find just the right royalty-free sound effect or music track for a video project.
Here are three of the most useful resources I’ve found. Both offer high-quality, royalty-free tracks at no cost.
FreeSound.org – A collaborative database of Creative Commons licensed sound effects.
PublicDomain4U.com – A treasure trove of links to music tracks which are now in the public domain.
Moby Film Music – A nice selection of tracks by Moby, specifically composed for non-profit/non-commercial and indy filmmakers.
