Editing Icecast (section)

==Technical details==
The Icecast server is capable of streaming audio content as [[Opus (audio format)|Opus]] or Vorbis<ref name="icecast">{{cite web|url=http://icecast.org/|access-date=13 March 2015|title=Icecast}}</ref> over standard [[HTTP]], video as [[WebM]] or [[Theora]]<ref name="icecast" /> over HTTP, and [[MP3]],<ref name="icecast" /> [[Advanced Audio Coding|AAC]],<ref name="icecast-news" /> and [[Nullsoft Streaming Video|NSV]]<ref name="icecast-news" /> over the [[SHOUTcast]] protocol. Theora, AAC, and NSV are only supported in version 2.2.0 and newer.

Icecast requires external programs, called "source clients", to originate the streams,<ref>{{Cite web|url=http://icecast.org/docs/icecast-2.4.1/introduction.html|title=Icecast Docs - Introduction|access-date=13 March 2015}}</ref> and the Icecast project includes a source [[Client (computing)|client]] program known as '''IceS'''.<ref>{{Cite web|url=http://icecast.org/ices|access-date=13 March 2015|title=IceS}}</ref> The source runs typically in the place where the audio is generated (e.g., a studio) and the Icecast server where a high-[[Bandwidth (computing)|bandwidth]] connection is available (e.g., a [[colocation centre]]). Since version 2.4.0 source clients can use plain HTTP standard PUT requests instead of the custom SOURCE method.<ref name="icecast-news" />
