Liquidsoap scripting language reference

The Source / … categories contain all functions that return sources. The Input functions are those which build elementary sources (playing files, synthesizing sound, etc.). The Output functions are those which take a source and register it for being streamed to the outside (file, soundcard, audio server, etc.). The Visualization functions are experimental ones that let you visualize in real-time some aspects of the audio stream. The Sound Processing functions are those which basically work on the source as a continuous audio stream. They would typically be mixers of streams, audio effects or analysis. Finally, Track Processing functions are basically all others, often having a behaviour that depends on or affects the extra information that liquidsoap puts in streams: track limits and metadata.

`add_skip_command`

Add a skip telnet command to a source when it does not have one by default.

Type:

Arguments:

(unlabeled) (of type source('b).{skip : () -> 'a}): The source to attach the command to.

`audioscrobbler.submit.full`

Submit songs using audioscrobbler, respecting the full protocol: First signal song as now playing when starting, and then submit song when it ends.

Arguments:

password (of type string)
host (of type string, which defaults to "post.audioscrobbler.com")
port (of type int, which defaults to 80)
source (of type string, which defaults to "broadcast"): Source for tracks. Should be one of: “broadcast”, “user”, “recommendation” or “unknown”. Since liquidsoap is intended for radio broadcasting, this is the default. Sources other than user don’t need duration to be set.
length (of type bool, which defaults to false): Try to submit length information. This operation can be CPU intensive. Value forced to true when used with the “user” source type.
delay (of type float, which defaults to 10.): Submit song when there is only this delay left, in seconds.
