DVD-Audio (DVD-A)
A format that allocates most of the DVD disc space to audio and is primarily used for
recording high-quality songs and music on DVD. Audio can be recorded on DVD in a
wide range of sampling frequencies between 44.1 kHz to 192 kHz and resolutions of 16,
20 or 24 bits, with up to six discrete channels.
A DVD-Audio disc contains two folders: AUDIO_TS and VIDEO_TS. AUDIO_TS stores
high-quality audio as .aob files along with still images (for use as menu backgrounds),
navigation, and text. A limited amount of conventional DVD-Video data can be recorded
in the VIDEO_TS folder.
DVD-Audio discs can only be played in DVD-Audio capable players.
