FLOSS alternative to subsonic, supporting its many clients

features

browsing by folder (keeping your full tree intact)
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 AlexKraak)
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
artist similarities and biographies from the last.fm api
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.
newer salt and token auth
tested on dsub, jamstash, sublime music, and soundwaves

installation

the default login is admin/admin.
password can then be changed from the web interface

$ apt install build-essential git sqlite libtag1-dev ffmpeg libasound-dev # for debian like
$ pacman -S base-devel git sqlite taglib ffmpeg alsa-lib                  # for arch like
$ go get go.senan.xyz/gonic/cmd/gonic
$ export PATH=$PATH:$HOME/go/bin
$ gonic -h # or see "configuration options below"

note: unfortunately if you do this above, you'll be compiling gonic locally on your machine (if someone knows how I can statically link sqlite3 and taglib, please let me know so I can distribute static binaries)

or else you can run in docker, available on dockerhub as sentriz/gonic

# example docker-compose.yml

version: '2.4'
services:
  gonic:
    image: sentriz/gonic:latest
    environment:
    - TZ
    # optionally, see more env vars below
    expose:
    - 80
    volumes:
    - ./data:/data             # gonic db etc
    - /path/to/music:/music:ro # your music
    - /path/to/cache:/cache    # transcode cache dir

    # set the following two sections if you've enabled jukebox
    group_add:
    - audio
    devices:
    - /dev/snd:/dev/snd

then start with docker-compose up -d

example nginx config with `GONIC_PROXY_PREFIX`

  location /gonic/ {
      proxy_pass http://localhost:4747/;
      # set "Secure" cookie if using HTTPS
      proxy_cookie_path / "/; Secure";
      # set "X-Forwarded-Host" header for last.fm connection callback
