Abbreviated as DVD-A, DVD-Audio is is a DVD format
designed to hold audio data, usually high-quality
music, similar in nature to how DVD-Video works.
The DVD-A format can hold limited data such as notes and images in addition to
the audio data. DVD-A offers 24-bit/192kHz (stereo) or 24-bit/96kHz (5.1) sound,
compared to16-bit/44 kHz for Audio-CDs. Depending on the number of layers
used, DVD-Audio discs can hold between 4 and 18GB of audio data. It is expected
that DVD-Audio will eventually replace CD audio. Currently DVD-Audio discs are
unusable in most regular DVD-Video players, the player must be a Universal DVD
player or one that displays the DVD-Audio logo. DVD-Audio standards are set by
the DVD Forum.
DVD Forum Ad-hoc association created for the purpose of exchanging and disseminating ideas and information about the DVD Format and its technical capabilities
How Stuff Works: The difference between DVD-audio and CDs DVD-audio has the potential to replace CDs because of the higher quality of the sound. However, there are several things that might prevent widespread acceptance of DVD-audio.
