Icecast is a streaming media project released as free software maintained by the Xiph.Org Foundation.

Icecast was created in December 1998/January 1999 by Jack Moffitt[5][6] and Barath Raghavan[6] to provide an open-source audio streaming server that anyone could modify, use, and tinker with.

Version 2, a ground-up rewrite aimed at multi-format support (initially targeting Ogg Vorbis) and scalability, was started in 2001 and released in January 2004.

Moffitt created Icecast, allowing the station to easily reach everywhere on campus without the necessity of FCC licensing or a transmitter upgrade.

[9] The source runs typically in the place where the audio is generated (e.g., a studio) and the Icecast server where a high-bandwidth connection is available (e.g., a colocation centre).
