Easy enough. I use GoldWave. I would drag the MP3 icon into Goldwave, duplicate it, and then cut back to what I wanted in the copy I created, then save it as MP3. Piece of cake.

I have (had?) Audacity, but never thought as much of it as of GoldWave, and consequently never really learned how to do it in Audacity.

Come to think of it, while you can download GoldWave for free, I'm not sure the free version does everything that you might want to do. I long since paid the nominal fee for full functions, and I don't now remember just what extras I got with that status.
