The Freesound Project

The Freesound Project aims to create a huge collaborative database of sounds -- audio snippets, samples, recordings, bleeps, etc., released under the Creative Commons Sampling Plus License. The Freesound Project provides new ways of accessing these samples, allowing users to  browse the sounds in using keywords, a "sounds-like" type of browsing and more. Users can up and download sounds to and from the database. In less that 7 months the database has grown to 30,000 users and over 10,000 samples.
