This a pretty cool tutorial from Le Ludo Blog on how to convert your proprietary mp3 file into the open Ogg Vorbis format.

His steps:

First we will install a little script made by Nathan Walp: mp32ogg

sudo apt-get install mp32ogg

It’s done, now to convert a file, open a terminal and do:

mp32ogg –quality=10 –delete –rename=%t /home/Musiques/file.mp3

Warning: it will delete the original file!! (remove “–delete” if you don’t want)

Seems simple enough, and will probably work on most distros.
