Audio Streaming can be fun, you can host your own show on internet with very little effort of installing softwares and equipments like a simple mic arrangement.
Live streaming, more specifically, means taking the audio and broadcasting it live over the Internet. The process involves an encoder to digitize the content, a audio publisher where the streams are made available to potential end-users and a content delivery network to distribute and deliver the content. The media can then be viewed by end-users live.
With documentation and help files its easy to host and make perfect use of your internet plus computer, with just sitting back in your office or bedroom.
Here is the list of 4 open source audio streaming software.
Icecast is a streaming media project released as free software maintained by the Xiph.org Foundation. It also refers specifically to the server program which is part of the project. Icecast was created in December 1998/January 1999 by Jack Moffitt and Barath Raghavan to provide an open source audio streaming server that anyone could modify, use, and tinker with. Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support (initially targeting Ogg Vorbis) and scalability.
PeerCast is a simple, free way to listen to radio and watch video on the Internet. It uses P2P technology to let anyone become a broadcaster without the costs of traditional streaming. This means you get to hear and watch stations not normally found on commercially funded sites. PeerCast offers considerable savings for broadcasters because they do not have to provide bandwidth for all of their listeners. A single 56K modem can be used to broadcast a radio station to the entire network.
