The Freesound Project aims to create a huge collaborative database of audio snippets, samples, and recordings, all released under the Creative Commons Sampling Plus License. Developed for the upcoming International Computer Music Conference 2005 in Barcalona, the site allows users to search by keyword, “sounds-like”, and even location (via geotags). Perfect for your next 80s cartoon theme song techno remix.
