NAME

liquidsoap - programmable audio stream generator

SYNOPSIS

liquidsoap [option...] [script.liq|expression|audiofile]

DESCRIPTION

liquidsoap is an extensible and flexible audio stream generator, mainly used for streaming to a shoutcast/icecast server. It is also possible to output in a file, to speakers or as raw PCM stream. liquidsoap can perform any audio processing, mixing streams together, applying filters, generating sound procedurally, there is no limit but your imagination. Input files can be accessed through the network, using samba, ftp or speech synthesis. Recognized formats are MP3, Ogg/Vorbis, AAC and WAV. Liquidsoap also inputs HTTP streams, or from a soundcard. The system features lots of programming operators, including user requests, time-based selection, sum. Many of these features are optional, so it is possible that they are not enabled in your installation.

script.liq is a liquidsoap script containing the settings and the source definitions. The script will be read from standard input if -- is given as script filename. Information about scripting liquidsoap is available on our website: http://savonet.sf.net/

If the parameter is an audio file then liquidsoap will attempt to decode it and will display the obtained metadata.

If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line scripts. In that case, the default is to have log messages on standard output and to disable the telnet server.
