<b>The Savonet Team is happy to welcome you in liguidsoap.</b>
On the left is a list of controllable nodes. Double-click a row to open the controller.
The <b>output</b> nodes are those which do something with your stream.
Some output directly to your speakers, some save your stream to a file, and
finally, some output to an icecast server for webradio.
A <b>mixer</b> is a mixing table. It has some input sources, and allows you
to select which one you want to play, tune the volume, etc.
<b>editable</b> and <b>queue</b> nodes are interactive playlists, in which
you can add files using drag-n-drop or builtin file browser. The editable is
more powerful, allows you to delete, insert at any place, not only at the
bottom.
Finally, a <b>playlist</b> is a non-interactive playlist, which list and
behaviour is hard-coded in the liquidsoap script. You can just see what will be
played next. (Actually, more could be coming soon, like changing random mode
and playlist file...)
