Subsonic is a free, web-based media streamer, providing access to your entire music collection wherever you are. Use it to share your music with friends, or to listen to your own music while at work. You can stream to multiple players simultaneously, for instance to one player in your kitchen and another in your living room.

Subsonic is designed to handle very large music collections (many thousand albums). It uses a combination of directory structure and tag parsing to organize the music. Although optimized for MP3 streaming, it works for any audio or video format that can stream over HTTP (for instance AAC and OGG). By using transcoder plug-ins, Subsonic supports on-the-fly conversion and streaming of virtually any audio format, including WMA, FLAC, APE, Musepack, WavPack, Shorten and OptimFROG.

If you have constrained bandwidth, you may set an upper limit for the bitrate of the music streams. Subsonic will then automatically resample the music to a suitable bitrate.

In addition to being a streaming media server, Subsonic works very well as a local jukebox. The intuitive web interface, as well as search and index facilities, are optimized for efficient browsing through large media libraries. Subsonic also comes with an integrated Podcast receiver, with many of the same features as you find in iTunes.

Subsonic is free software distributed under the LGPL open-source license.

Requirements

Subsonic works with most operating systems, including Windows, Linux, Mac and Solaris. The Windows installer includes all you need, and installs Subsonic as a service. If you opt for the WAR download, you must install Java (version 5.0 or later) and a JSP container such as Tomcat (version 5.5 or later), both of which are available at no charge. There is also a stand-alone version available which doesn't require Tomcat.

To receive streams you need a web browser (tested on recent versions of Firefox, Opera and IE) and a media player (Winamp, Windows Media Player etc). Refer to the FAQ for a list of recommended players.

I'm looking for volunteers who'd like to translate Subsonic to new languages, and to improve existing translations. Interested? Please read this.
