LibreTime is a radio station automation system that supports web casting. It
is built from as a community fork of SourceFabric's Airtime radio station
automation system. It provides a web interface where you can upload tracks and
arrange them to play at certain times via a schedule. The software also allows
different users to take one roles such as DJ, Program Manager and Admin with
various levels of permissions. You can for instance assign a DJ to a certain
time slot and they will be able to login and upload shows only during that
time period. In addition there is live streaming with user based
authentication where a user can only stream during the show times they are
assigned.

Beyond this LibreTime also provides automatic podcast downloading and
scheduling and other allows other advanced automation with a metadata based
track selection system called smartblocks. It allows you to select certain
tracks in your library to play based upon a variety of options such as genre,
length and even BPM. Also LibreTime has the ability to automatically
rebroadcast other stations via relaying webstreams.

At this time we still consider LibreTime alpha level software because there is
a lot of development going on and we still haven't solved all of the bugs. In
the near future we are aiming to release a version 3 beta and then possibly a
stable release. It is completely self-hosted but can be setup on a VPS running
Ubuntu 16.04 or above (the soon to be released alpha.7 release will support
Ubuntu 18.04 and above). You will want at least 1GB of ram on your server as
LibreTime runs with a lot of services such as rabbitMQ, Postgresql, Apache,
Liquidsoap & Python scripts.

The community is active and we use the (C4 - Collective Code Construction
Contract) from ZeroMQ to direct how we handle various code commits and
contributions. You can check out our github at
