What is Airsonic?

Airsonic is a free, web-based media streamer, providing ubiquitous access to your music. 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.

Airsonic is designed to handle very large music collections (hundreds of gigabytes). 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, Airsonic supports on-the-fly conversion and streaming of virtually any audio format, including WMA, FLAC, APE, Musepack, WavPack and Shorten.

If you have constrained bandwidth, you may set an upper limit for the bit rate of the music streams. Airsonic will then automatically re sample the music to a suitable bit rate.

In addition to being a streaming media server, Airsonic 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. Airsonic also comes with an integrated Podcast receiver, with many of the same features as you find in iTunes.

Based on Java technology, Airsonic runs on most platforms, including Windows, Mac, Linux and Unix variants.

History

The original Subsonic is developed by Sindre Mehus. Subsonic was open source through version 6.0-beta1, and closed-source from then onwards.

Libresonic was created and maintained by Eugene E. Kashpureff Jr. It originated as an unofficial(“Kang”) of Subsonic which did not contain the Licensing code checks present in the official builds. With the announcement of Subsonic’s closed-source future, a decision was made to make a full fork and rebrand to Libresonic.

Around July 2017, it was discovered that Eugene had different intentions/goals for the project than some contributors had. Although the developers were hesitant to create a fork as it would fracture/confuse the community even further, it was deemed necessary in order to preserve a community-focused fork. To reiterate this more clearly:

Airsonic’s goal is to provide a full-featured, stable, self-hosted media server based on the Subsonic codebase that is free, open source, and community driven.

Pull Requests are always welcome. Keep in mind that we strive to balance stability with new features. As such, all Pull Requests are reviewed before being merged to ensure we continue to meet our goals.
