The Freesound Project was officially launched on April 5, 2005 in the context of the 2005 International Computer Music Conference earlier that year. It is a project of the Music Technology Group of Pompeu Fabra University. Bram de Jong is responsible for developing and administrating the Freesound website.
Children of Men was the first major motion picture known to legally use a sample from Freesound in its production. The sound used was " male_Thijs_loud_scream.aiff" posted by the user thanvannispen, and the film properly attributes the sample in the credits.
The features of freesound are designed to make the sound files on the website easy to index, search, and browse. The Sampling Plus License permits the sampling and/or transformation of all the sounds on the site to create derivative works, even for profit (as long as they are not used to advertise an unrelated product.) Verbatim copying is also permitted. Since the Sampling Plus License stipulates 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.
