Quod Libet – GTK+-based audio player

Quod Libet is a music management program. It provides several different ways to view your audio library, as well as support for Internet radio and audio feeds. It has extremely flexible metadata tag editing and searching capabilities. It’s designed around the idea that you know how to organize your music better than the developers do.

Quod Libet lets you make playlists based on regular expressions and regular searches. The software also lets you display and edit any tags you want in the file. And it lets you do this for all the file formats it supports — Ogg Vorbis, FLAC, MP3, Musepack, and MOD.

Quod Libet is an GTK+-based application written in Python.

Also included is Ex Falso, a tag editor that has the same editing features found in Quod Libet, but does not play audio files.

Features include:

  • Audio Playback:
    • ReplayGain support.
    • Multimedia key support.
    • Real shuffle mode, that plays the whole playlist before repeating.
