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.
