DVD Audio

The DVD-Audio format is designed to provide the highest possible audio fidelity. The audio quality of DVD-Audio far exceeds that availbale on DVD-Video and CDs.

The DVD-Audio specification is capable of holding audio information of many different types and formats. The specifications and idustry standards for DVD-Audio are decided by an industry group named The DVD Forum. (a lot of useful information can be found on their site).

The format provides for audio in stereo and in multi-channel surround in a wide range of configurations. In addition to audio, a DVD-Audio disk can contain a limited amount of video or still images. Up to 16 graphic stills can be associated with each track and on-screen displays can be used for lyrics and disc navigation. A DVD-Audio disc can also include audio tracks recorded in the DVD-Video specification (Dolby Digital and DTS) for compatibility with DVD-Video players.

In the stereo realm, maximum sample rates of 176 or 192 kHz at 24 bit resolution can be used, while in 5.1 channel surround, audio can be delivered at as high a resolution as 96 kHz and 24 bit. Contrast this with the maximum 96/24 stereo resolution and 48/16 surround resolution in the DVD-Video specification.
