So freedom is important but so is working with MP3 files. The default Audacity package on Fedora does not have MP3 support which is understandable but a pest.

So here is how to get Audacity with MP3 support.

Firstly you need the rpmfusion repos,

su -c 'yum localinstall –nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

then its as easy as

sudo yum install audacity-freeworld

and it is done.
