Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I'm running an Ubuntu server environment with icecast-2.3.2 and ices-0.4.0 to enable internet-radio streaming.

I have a directory with music files, mostly MP3, let's call it /PATH/TO/MUSIC. I also have directories with jingles and podcasts. /PATH/TO/JINGLES and /PATH/TO/PODCASTS.

So far my server is up and running.

What works:

  • Creating daily random playlists from the music-directory using a script and a cron-job.
  • Running an IceCast2-Server and streaming the playlist file using IceS.

My question now is:

  • How to play podcasts and jingles at specific times? For example every full hour a certain jingle, or every Thursday at 8 p.m. a certain podcast?

I've tried to search the internet on this topic but it seems there is no "one final solution" for this radio-automation issue and it also seems a lot of solutions are rather hacky, aren't they?

Keep in mind this is a server environment, solutions with GUI wont help.

I appreciate any hints and experiences on this topic!

The answer is: liquidsoap.

liquidsoap, a swiss-army knife for multimedia streaming, notably used for netradios and webtvs. It has tons of features, it's free and it's open-source!

It took me some days to understand how streams are generated. liquidsoap consists of little scripts which describe the stream parameters. a simple script which loads and plays a mp3-playlist, let's call it basic.liq, is show below:

#!/usr/bin/liquidsoap

# load a playlist file
stream = playlist("/path/to/playlist.pls")

# output the playlist to icecast
source = output.icecast(%mp3, host="localhost", port="8000",
         mount="listen.m3u", password="hackme")
source(stream)

test the script with:

$ liquidsoap --check ./basic.liq

and start the script with:

$ liquidsoap ./basic.liq &

but liquidsoap is much more powerful. for example, to play a jingle every full hour, simply add:

# add a jingle every full hour
jingle = single("/path/to/jingle.mp3")
add([stream,switch([({0m0s},jingle)])])

but a lot more features are described at the homepage:

  • static or dynamic playlists
  • time-based selection of the audio source
  • quota- or time-based insertions or mixes of jingles
  • live DJ interventions
  • interactive user requests
  • fully-customizable transitions, e.g. crossfading
  • speech-synthesis of track metadata
  • simple access to remote files
  • and much more

It's worth to take a look at the quick start guide, a more complex example and the documentation.
