SvOlli's Little Audio Related Thingies, or SLART for short, is a compilation of rather simple programs that are related to audio files: it consists of a player (Partyman), a CD ripper, a tag editor, a downloader for music files that also works with MySpace, and some other tools. These programs can communicate with each other via UDP, so a newly ripped track can be automatically queued in the player, for example.
The core component, Partyman, is a simple double-deck audio player that keeps on playing as long as it's running. If it finds entries in its own playlist, these are played, otherwise random tracks are chosen. It also crossfades between the tracks automatically. The main purpose for this program is providing some background music for a party, respecting requests.
