Quod Libet is an audio player that works on macOS, Linux and Windows. It is open-source and is designed to work the huge libraries containing tens of thousands of songs. In fact, this is the main feature of Quod Libet – to tag and add thousands of tracks to its library. The library is made searchable using tags, albums, artists and other things. Even with huge libraries, Quod Libet can find a song in a fraction of second as you type in the search field.
Quod Libet is available for Windows in both portable format and also as an installer. It uses Python for its internal operations and so it might take a while for it to appear on your screen when you launch it for the very first time. In the Quod Libet options, you can define one or more folders that are to be watched for new music files, and it will update the library to add the new songs that you have added to those folders. Quod Libet supports all the popular audio file formats such as MP3, FLAC, OGG Vorbis, MIDI, WMA, M4A etc. It lets you display and edit tags of all the audio files for the above mentioned formats.
Quod Libet has a simple user interface as you would expect from some of older Linux music players. But it makes things much easier, you can simply select a song and click on the “Play” button to start playing that song. The powerful feature of the user interface is the ability to search through a large library using RegEx search. It also supports simple text search.
It uses Python for internal working and supports all Python based plugins. You can enhance Quod Libet with plugins and add support for Shoutcast, Podcast, CDDB, MusicBrainz and so on. It is not really an audio player for a beginner (who would instead love Foobar2000 or XMPlay), but advanced users are going to love configuring it for their own use.
