Public Domain Sound Library Volume 4

Over 100 environmental loops in one which are all public domain from freesound.org

All sound info is in the cue point for each sound.

These are perfect backgrounds for videos, for games, or maybe songs of your own? There is lots of different loops for everyone :)

Since these are public domain, you are not required to give credit for any of the sounds (including this collection), but if you want to thank an artist and/or tell them where you used it, just copy/paste the file number into freesound's search field and it will help you find the file page.

Important:
If you intend to register a copyright with the government for works you created using public domain sounds, you must indicate them in the application process (limit of claims section) because you cannot copyright public domain sounds.
