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.

This manual page is only a short reference for Quod Libet. Complete documentation is available at http://code.google.com/p/quodlibet/wiki/Guide.

Album covers should be put in the same directory as the songs they apply to, and have "folder", "front", or "cover" in their filenames. If you want to store multiple albums in the same directory but keep distinct cover images, the name of the appropriate image file must contain the labelid tag value, e.g. COCX-32760 cover.jpg.

Many places in Quod Libet allow you to use "tied tags". Tied tags are two tag names joined together with a "~" like "title~version" or "album~part". Tied tags result in "nice" displays even when one of the tags is missing; for example, "title~version" will result in Title - Version when a version tag is present, but only Title when one isn't. You can tie any number of tags together.

All of Quod Libet's search boxes support advanced searches of the following forms:

tag = value
tag = !value
tag = "value"
tag = /value/
tag = &(value1, value2)
tag = |(value1, value2)
!tag = value
|(tag1 = value1, tag2 = value2)
&(tag1 = value1, tag2 = value2)
#(numerictag < value)
#(numerictag = value)
#(numerictag > value)

The 'c' postfix on strings or regular expressions makes the search case-sensitive. Numeric values may be given as integers, floating-point numbers, MM:SS format, or simple English, e.g. "3 days", "2 hours".

See http://code.google.com/p/quodlibet/wiki/Guide_Searching.

All internal tags begin with a ~ character. Non-numeric internal tags are ~base‐ name, ~dirname, ~filename, ~format, ~length, ~people, and ~rating. Numeric internal tags are ~#added, ~#bitrate, ~#disc, ~#lastplayed, ~#laststarted, ~#length, ~#mtime, ~#playcount, ~#skipcount, and ~#track.

See http://code.google.com/p/quodlibet/wiki/Guide_InternalTags.

Quod Libet allows you to rename files based on their tags. In some cases you may wish to alter the filename depending on whether some tags are present or missing, in addition to their values. A common pattern might be

<tracknumber>. <title~version>

You can use a '|' to only text when a tag is present:

<tracknumber|<tracknumber>. ><title~version>

You can also specify literal text to use if the tag is missing by adding another '|':

<album|<album>|No Album> - <title>

See http://code.google.com/p/quodlibet/wiki/Guide_Renaming.

Quod Libet uses GStreamer for audio playback. It tries to read your GConf GStreamer configuration, but if that fails it falls back to osssink. You can change the pipeline option in ~/.quodlibet/config to use a different sink, or pass options to the sink. For example, you might use esdsink or alsasink device=hw:1.

See http://code.google.com/p/quodlibet/wiki/Guide_AudioBackends.

~/.quodlibet/songs

A pickled Python dict of cached metadata. Deleting this file will remove all songs from your library.

~/.quodlibet/config

Quod Libet's configuration file. This file is overwritten when Quod Libet exits.

~/.quodlibet/current

A "key=value" file containing information about the currently playing song.

~/.quodlibet/control

A FIFO connected to the most-recently-started instance of the program. --next, --previous, etc., use this to control the player.

~/.quodlibet/plugins/

Put plugins (from http://code.google.com/p/quodlibet/wiki/Guide_Plugins) here.

~/.quodlibet/browsers/

Put custom library browsers here.
