Freesound is a collaborativerepository ofCreative Commons licensedaudio samples, and non-profit organisation, with more than 500,000 sounds and effects (as of May 2021),[1] and 8 million registered users (as of March 2019). Sounds are uploaded to the website by its users, and cover a wide range of subjects, fromfield recordings to synthesised sounds. Audio content in the repository can betagged and browsed byfolksonomic means as well as standard text-based search. Audio content in the repository is also analysed using the open-source audio analysis tool Essentia, which powers the similarity search functionality of the site.Freesound has aRESTful API through which third-party applications can access and retrieve audio content and its metadata.
Freesound originally used theCC Sampling Plus license for all samples, but has since switched to usingCC0,CC BY, andCC BY-NC. Older samples remain under Sampling Plus unless their uploaders haverelicensed them.
All of these licenses allow use and distribution of the samples (modified or unmodified) for non-commercial purposes, and in the case of CC0 and CC BY also for commercial purposes. The Sampling Plus license did not allow unmodified samples to be distributed commercially, and therefore, like CC BY-NC, fails theDefinition of Free Cultural Works and theDebian Free Software Guidelines, and is not free enough to be used on Wikipedia, free software programs, and other projects requiringfree content.
The Freesound Project was officially launched on April 5,2005 in the context of the 2005International Computer Music Conference. It is a project of theMusic Technology Group ofUniversitat Pompeu Fabra,Barcelona. Frederic Font is heading the team responsible for developing and administrating the Freesound website.[2]
Children of Men is the first majormotion picture known to legally use a sample from Freesound in its production. The sound used is "male_Thijs_loud_scream.aiff" posted by the user thanvannispen, and the film properly attributes the sample in the credits.[3][4]
The features of Freesound are designed to make the sound files on the website easy to index, search, and browse. Since the licenses used (exceptCC0) stipulate that the authors of the original work must be credited in the derivative work, the site is capable of automatically generating an attribution list to make this easier.
The Freesound platform is based on technology developed by the Music Technology Group of the Pompeu Fabra University, Barcelona.
