It features multiple turntables, realtime effects (built-in as well as LADSPA plugin effects), a sequencer, and an easy-to-use GTK+ GUI.

audio convert is a script that converts between WAV, Ogg, MP3, MPC, FLAC, APE, AAC, and WMA files. It has an easy-to-use interface that makes it possible to fill in the tags for a few formats, copy the tags from input files into the new files, and choose the quality of compression. The script was initially designed for the Nautilus file browser and can be easily installed into Nautilus by using the installer provided with the script. You can then right-click on files and choose "audio-convert" from the "scripts" menu. The script is also known to work on rox or directly from a shell.
Freedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space within one or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.

It has extensive filtering capabilities, customizable random modes, customizable window layouts, mass-tagging, and more.
