DVD-Audio

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.
