What are DVD-Audio discs?
DVD-Audio (also abbreviated as DVD-A) is a digital format designed to provide high-resolution audio on a DVD disc. DVD-Audio is not the same as a standard DVD-Video disc and generally DVD-Audio discs have very limited video content. DVD-Audio discs can support from mono up to 6 channels of audio. Mono and Stereo audio tracks are supported up to 24-bit/192kHz, and 5.1 surround tracks are supported up to 24-bit/96kHz. Discs can have multiple tracks, so for example a DVD-A disc can contain both a 24-bit/192kHz stereo audio track as well as a 24-bit/96kHz 5.1 surround audio track. The high-resolution audio on DVD-A discs is stored on the disc in Linear PCM format. The audio may be stored on the disc either in an uncompressed format, or compressed using Meridian Lossless Packing (MLP). Depending on the amount of audio tracks on the disc, compression may be necessary. While a DVD-Audio player is required in order to access and play the high-resolution audio on a DVD-A disc, most DVD-A discs
