DVD-Audio takes advantage of the large storage capacity, speed and flexibility possible with DVD. DVD-Audio provides for audio in
stereo and in multi-channel surround in a wide range of specifications. In addition to audio, a DVD-Audio disk can contain a
limited amount of video, which can be used to display text, such as lyrics or notes; or stills such as a photo album. Up to 16
graphic stills can be associated with each track and on-screen displays can be used for lyrics and disc navigation.
However, real advantage of the DVD-Audio specification over DVD-Video and CD is in the significantly increased quality of the
PCM audio format. PCM or "Pulse-Coded-Modulation" is the audio format standard for CD’s.
DVD-Audio supports a significantly higher quality of PCM audio than is possible on CD. DVD-Audio PCM can be recorded with a
range of frequencies that are more than four times that of a CD; giving instruments a liveliness and expression that is not
possible on a CD. DVD-Audio PCM also has a much greater dynamic range that possible on a CD - making “louds” louder and
“quiets” quieter. The greater storage capacity of DVD’s allows for much more music to be recorded than possible on CD's.
