FLOSS alternative to subsonic, supporting its many clients

irc #gonic on libera.chat  |  matrix #gonic:libera.chat

features

• browsing by folder (keeping your full tree intact) see here
• browsing by tags (using taglib - supports mp3, opus, flac, ape, m4a, wav, etc.)
• on-the-fly audio transcoding and caching (requires ffmpeg) (thank you spijet)
• jukebox mode (thank you lxea)
• support for podcasts (thank you lxea)
• pretty fast scanning (with my library of ~50k tracks, initial scan takes about 10m, and about 6s after incrementally)
• multiple users, each with their own transcoding preferences, playlists, top tracks, top artists, etc.
• last.fm scrobbling
• listenbrainz scrobbling (thank you spezifisch, lxea)
• artist similarities and biographies from the last.fm api
• support for multi valued tags like albumartists and genres (see more)
• 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

multi valued tags (v0.16+)

gonic can support potentially multi valued tags like genres and albumartists. in both cases gonic will individual entries in its database for each.

this means being able to click find album "X" under both "techno" and "house" for example. or finding the album "My Life in the Bush of Ghosts" under either "David Byrne" or "Brian Eno". it also means not cluttering up your artists list with "A & X", "A and Y", "A ft. Z", etc. you will only have A, X, Y, and Z.

the available modes are:

value	desc
multi	gonic will explictly look for multi value fields in your audio metadata. software like musicbrainz picard or beets can set set these (soon)
delim <delim>	gonic will look at your normal audio metadata fields like "genre" or "album_artist", but split them on a delimiter. for example you could set -multi-value-genre "delim ;" to split the single genre field on ";"
none (default)	gonic will not attempt to do any multi value processing

multiple folders support (v0.15+)

gonic supports multiple music folders. this can be handy if you have your music separated by albums, compilations, singles. or maybe 70s, 80s, 90s. whatever.

if you're running gonic with the command line, stack the -music-path arg

$ gonic -music-path /path/to/albums -music-path /path/to/compilations

if you're running gonic with ENV_VARS, or docker, try separate with a comma

GONIC_MUSIC_PATH=/path/to/albums,/path/to/compilations

if you're running gonic with the config file, you can repeat the music-path option

music-path /path/to/albums
music-path /path/to/compilations

after that, most subsonic clients should allow you to select which music folder to use. queries like show me "recently played compilations" or "recently added albums" are possible for example.

directory structure

when browsing by folder, any arbitrary and nested folder layout is supported, with the following caveats:

• Files from the same album must all be in the same folder
• All files in a folder must be from the same album
