Like the title says, is there a free site or program which will allow me to edit or cut parts off of an mp3 song.

For instance on a live track where there is a bunch of talking by the band before the next track starts...is there some program where i can cut this part and just keep the main song intact?

Thanks in advance for any help!
How come i never knew about this site? :-/
Well, if that does the job, thanks a lot
