Supysonic

Supysonic is a Python implementation of the Subsonic server API.

At this time, it only supports what I need and lacks most features a real Subsonic server would provide. Current supported features are:

basic browsing (by folders or tags)
streaming (obviously, the collection scanner only looks for MP3s though)
random playlists
cover arts (cover.jpg files in the same folder as music files)
Last.FM scrobbling

Installation

Supysonic can run as a standalone application (not recommended for a "production" server) or as a WSGI application (on Apache for instance). But first:

Prerequisites

Python 2.7
Flask >= 0.7 (pip install flask)
SQLAlchemy (apt-get install sqlalchemy)
Python Imaging Library (apt-get install python-imaging)
simplejson (apt-get install python-simplejson)
requests >= 0.12.1 (pip install requests)
eyeD3 >= 0.7 (pip install eyed3)

Configuration

Supysonic looks for two files for its configuration: ~/.supysonic or /etc/supysonic (in this order). Options are set using the KEY = VALUE syntax. String values must be quote-enclosed.

Available settings are:

DATABASE_URI: a SQLAlchemy database URI I personnaly use SQLite (sqlite:////var/supysonic/supysonic.db), but it might not be the brightest idea for large libraries.
CACHE_DIR: path to a cache folder. Mostly used for resized cover art images.
LOG_FILE: path and base name of a rolling log file.
LASTFM_KEY: Last.FM API key to enable scrobbling
LASTFM_SECRET: Last.FM API secret matching the key.

Running as a standalone server

It is possible to run Supysonic as a standalone server, but it is only recommended to do so if you are hacking on the source. A standalone won't be able to serve more than one request at a time.

To start the server, just run the main.py script.

python main.py

The server will then be available at http://server:5000/

Running as a WSGI application

Supysonic can run as a WSGI application with the main.wsgi file. But first you need to edit this file at line 4 to set the path to the Supysonic app folder.

To run it within an Apache2 server, first you need to install the WSGI module and enable it.

apt-get install libapache2-mod-wsgi
a2enmod wsgi
service apache2 reload

Next, edit the Apache configuration to load the application. Here's a basic example of what it looks like:

WSGIScriptAlias /supysonic /path/to/supysonic/main.wsgi
<Directory /path/to/supysonic>
	WSGIApplicationGroup %{GLOBAL}
	Order deny,allow
	Allow from all
</Directory>

With that kind of configuration, the server address will look like http://server/supysonic/

Quickstart

The first time you run the server, open its URL to set the initial configuration. You'll be asked to create a first user. This user will be an admin of the server.

Once the first user created, log in to the app. Then you can add other users or manage folders. Folders are where your music is located. Add one, then hit the scan button. The scanning process might take some time on large libraries, so be patient. Your browser might even timeout even if the process is still running. Once scanning is done, you can enjoy your music with the client of your choice.
