"DVD-Audio is not the same as the audio formats used for the
soundtracks in DVD movies, which are various lossy formats. It is a
separate audio-only standard that supports very high digital audio
resolutions, up to 24 bits depth/192 kHz sampling rate for
two-channel stereo, and up to 24/96 (uncompressed) per channel for
5.1 surround. In comparison, CD-Audio is 16/44.1, and is
two-channel stereo only."
