Gonic

Gonic provide a backend compatible with the Subsonic API for all your music clients.

features:

• browsing by folder (keeping your full tree intact)
• browsing by tags - supports mp3, opus, flac, ape, m4a, wav, etc...
• on-the-fly audio transcoding and caching
• jukebox mode
• support for podcasts
• pretty fast scanning (with my library of ~27k tracks, initial scan takes about 10m, and about 5s after incrementally)
• multiple users, each with their own transcoding preferences, playlists, top tracks, top artists, etc.
• last.fm scrobbling
• listenbrainz scrobbling
• artist similarities and biographies from the last.fm api
• support for multi valued tags like albumartists and genres
• a web interface for configuration (set up last.fm, manage users, start scans, etc.)
• support for the [album-artist tag, to not clutter your artist list with compilation album appearances
• written in Go, so lightweight and suitable for a raspberry pi, etc. (see ARM images below)
• newer salt and token auth
• tested on airsonic-refix, symfonium, dsub, jamstash, sublime music, soundwaves, stmp, strawberry, and ultrasonic
