Quod Libet (software)

Quod Libet is a cross-platform free and open-source audio player, tag editor and library organizer.

The main design philosophy is that the user knows how they want to organize their music best; the software is therefore built to be fully customizable and extensible using regular expressions and boolean logic.

Quod Libet is based on GTK and written in Python, and uses the Mutagen tagging library.

Quod Libet is available on most Linux distributions, macOS and Windows, requiring only PyGObject, Python, and an Open Sound System (OSS), ALSA or JACK compatible audio device.

The XFCE desktop ISO image provided by the Debian project installs Quod Libet as the default audio player.

The tag editor interface, used by both Quod Libet and Ex Falso , allows any tag to be changed as well as any file to be renamed or moved.
