About Madsonic

Madsonic is a web-based media library and media streamer with jukebox functionality. Based on Java technology, Madsonic runs on most platforms, including Windows, Mac, Linux, OSX, and Unix variants.

If you have constrained bandwidth, you may set an upper limit for the bitrate of the music streams. Madsonic will then automatically resample the music to a suitable bitrate. In addition to being a streaming media server, Madsonic 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.

Clients can connect via the built in website or with many other clients that support the Madsonic/Subsonic REST API.

Madsonic is open-source software licensed under GPL.
