Audacity, and avoiding the trap in NO MP3 support, in Fedora

There are 2 versions in Fedora for Audacity install - the free and non-free.

If you want to be able to import audio in the MP3 format (there may be other formats other than MP3 that are supported), make sure you select the non-free version of Audacity in the Software list, named:
audacity-freeworld-2.0.0-1.fc18

as opposed to the free version I installed named
audacity-2.0.2-2.fc18

Correcting my mistake of installing the free version of Audacity, I first suspected to add MP3 codecs support in my system doing this (gotten from a DuckDuckGo search):

su -
yum install gstreamer-plugins-bad gstreamer-plugins-ugly

Yes, it did find some packages to download, and yes, it did install.  This probably worked because I already installed the RPMFusion package beforehand (see my earlier post).
 
But it didn't fix the problem: going back to Audacity and attempting a MP3 import still produced the error message, "This version of Audacity was not compiled with mp3 support."

This fixed the problem, based on a tip found in the Fedora Forums.

su - 

yum remove audacity
yum install audacity-nonfree
