Audacious is an advanced audio player. It is free, lightweight, based on GTK2, runs on Linux and many other *nix platforms and is focused on audio quality and supporting a wide range of audio codecs. Its advanced audio playback engine is considerably more powerful than GStreamer. Audacious is a fork of Beep Media Player (BMP), which itself forked from XMMS.
