Downmixing can only be done to two-channel stereo, not to other configurations, such as 4.0 quad. If no native stereo audio exists on the disc, the DVD-Audio player may be able to downmix the 5.1-channel audio to two-channel stereo audio if the listener does not have a surround sound setup (provided that the coefficients were set in the stream at authoring).
In uncompressed modes, it is possible to get up to 96/16 or 48/24 in 5.1, and 192/24 in stereo. Channel/resolution combinations that would exceed this need to be compressed. The maximum permissible total bit rate is 9.6 Megabits per second. For example, the front speakers could be 96/24, while the surrounds are 48/20.Īudio is stored on the disc in Linear PCM format, which is either uncompressed or losslessly compressed with MLP (Meridian Lossless Packing).
Also, the channels of a track can be split into two groups stored at different resolutions. For instance, a DVD-Audio disc may contain a 96 kHz/24-bit 5.1-channel audio track as well as a 192 kHz/24-bit stereo audio track.

(The ".1" denotes a low-frequency effects channel (LFE) for bass and/or special audio effects.)Ĭompared to the Compact Disc, the much higher capacity DVD format enables the inclusion of either: Audio specificationsĭVD-Audio offers many possible configurations of audio channels, ranging from single-channel mono to 5.1-channel surround sound, at various sampling frequencies and sample rates. DVD-Audio remains a niche market but some independent online labels offer a wider choice of titles. As of June 2019, Amazon lists only 155 albums available on "Audio DVD". DVD-Audio was in a format war with Super Audio CD (SACD), and along with consumers' tastes tending towards downloadable music, these factors meant that neither high-quality disc achieved considerable market penetration DVD-Audio has been described as "extinct" by 2007. The first discs entered the marketplace in 2000. DVD-Audio uses most of the storage on the disc for high-quality audio and is not intended to be a video delivery format.
