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.
