(.exe file, 3.6 MB) - Audiograbber is a beautiful piece of software that grabs digital audio from cd's. Audiograbber can automatically normalize the music, delete silence from the start and/or end of tracks, and encode them to a variety of formats including MP3. Audiograbber can download and upload disc info from freedb, an Internet compact disc database. You can even record your vinyl LP's or cassette tapes with Audiograbber and make wav's or MP3's of them. There are a lot more functions in Audiograbber, but to put it simply: Audiograbber has the most features one can wish from such a program!
