This work is licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License

All sounds in the Opsound pool are released under the Creative Commons Attribution-ShareAlike license (a copyleft license similar to those used in the free and open source software communities) or are placed in the public domain (the license information for each song can be found under the song link).

This means you are free (and encouraged) to download works, make copies, share them, include them in other works, remix and rearrange them, and even sell them.

The Attribution-ShareAlike license requires that you attribute the works to their original authors/musicians (attribution), and that any derivative works (anything you make using the sound files) be licensed under the same license (share alike).

Film/Video Makers: Please Note The license defines film and video works using licensed music as soundtrack material as "derivative works": "For the avoidance of doubt, where the Work is a musical composition or sound recording, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered a Derivative Work for the purpose of this License." [cc by-sa 2.5 legal code] This means that you must release the resulting film or video under the identical license. If you do not wish to do so, you can still contact the artists directly and make any kind of arrangement with them that is mutually agreeable. Opsound artists are typically delighted to have their work included in films and videos, and often willing to make allowances for noncommercial and low-budget projects.

Works placed in the public domain are free from any copyright restrictions, and you may do whatever you like with them.

Links to the license or public domain dedication are located in the info line below the title & description of each song.

If you want to use music from the pool, a visit to the Creative Commons website for more details & explanation is strongly recommended.

Keep in Touch

If you use work from the pool as part of something you make publicly available, you are encouraged to email us and let us know, and of course to let the original artist know as well. If you are making a remix, deconstruction, rearrangement, or recombination of sound pool sounds, you are encouraged to enter that work back into the pool.

About Commercial Uses

The Creative Commons license used by Opsound does not restrict commercial use of the sound files. However, you are strongly encouraged to get in contact with the artist if you wish to do this, and to make arrangements to share any financial benefits. It is hoped that we can develop a community that operates with a great deal of freedom and which uses that freedom in a way that is both generous and ethical.
