ccHost is an open source (GPL licensed) project that provides web-based infrastructure to support collaboration, sharing, and storage of multi-media using the Creative Commons licenses and metadata. It is the codebase used by ccMixter and other sites.

Besides its focus on sharing content, ccHost differentiates itself from other multi-media hosting programs by emphasizing the reuse (a.k.a. remixing) of content between artists, not only between artists on any given installation of ccHost, but between all installations across the web and any web site that implements the Creative Commons Sample Pool API, including non-ccHost sites such as the freesound project.
