What does "digital audio" mean?

"Digital" means information stored in a binary format (made up of ones and zeroes). In general, the term refers to using computers to record, play, and manage audio stored in a digital format. Digital audio systems can be used to transfer audio from a tape, CD, or live performance into a format playable on computers (like AIFF or WAV files); make edits (like cuts, fades, and special effects) to those audio files; and output audio files back to tape or CD media.
