Much of the material in this book is fundamental information that applies to digital audio on any type of computer or operating system; however, we do include material specific to Mac OS X and Windows XP, where appropriate. This book includes a good deal of software-specific instructions, so we’ve done our best to make everything as current as possible. Because there is not enough room to cover all the details of these programs, we focus on the most common features and tasks. In the case of programs that come in both “lite” and full versions, the instructions we include are based on the full version unless otherwise noted. Don’t worry if you use a program not covered in the book; most of the procedures and concepts apply to similar programs. The applications we cover include iTunes 4.7, Media Jukebox 8.0, Musicmatch Jukebox 9, Peak 4.0, and Sound Forge 7.0.
