I need to cut up a long CD audio file (a single performance from which I need highlights) and add fade ins and fade outs at the beginning and end of each clip. Are there any freeware options that won't compromise the sound quality too much? (I really don't want to squander cash on such a simple, one-time operation.) I've downloaded a few demos of full-featured products, but they won't le me save my work. HELP!
