MP3 editing
I have tried multiple free and not-so-free programs to edit my music and to make new tracks with sounds and samples... and I have to say that Audacity is great.
It is the easiest I have found so far for changing bitrates in MP3s...
Audacity is free and can be downloaded here:
http://audacity.sourceforge.net/
For exporting and saving in MP3 format, you will need a LAME.dll, but it can be found either on their site or the Audacity program will direct you to the file when it is needed.
