GarageBand lets you create music of your very own. If you're already a musician, you'll probably flip over GarageBand; it combines the CD-quality samples of Apple's Soundtrack software with the hard-disk recording features of Digital Performer and the canned rhythm tracks of Band in a Box. But what's really mind-boggling is the way this program can turn the inspiration of musical novices into commercial-sounding demos. Imagine how many thousands of singers and instrumentalists, though blessed with enormous native talent, remain undiscovered because they lack recording studios and backup bands. For them, GarageBand may open a lot of doors--or just offer a lot of fun.GarageBand: The Missing Manual is an authoritative, witty guide to constructing digital recordings with GarageBand.
