DVD-Audio is available with storage capacities of 4.7 GB, 8.5 GB and 17 GB. The high playback quality is due to the various sampling rates of 44.1, 48, 96, 176.4 and 192 kHz and the various quantizations of 12, 16, 20 and 24 bits. This results in a dynamic range of 144.5 dB at the 192 kHz samplerate and 24 bit sampling depth.
The DVD-Book C contains the specifications for audio, the possible software applications and the functions integrated in the DVD drive. Up to six digital audio tracks can be stored on a DVD-Audio in compressed and uncompressed form. MPEG-1, MPEG-2 and Dolby Digital are used for lossy compression, while MLP compression is used as lossless compression.
DVD-Audio also has a special audio zone, the Compressed Audio Zone, where pre-compressed copies of music tracks can be stored. These can then be transferred directly to MP3 players and multimedia players in a protected format. The audio codec EH- AAC, or aacPlus, has been made mandatory for this Compressed Audio Zone. DVD-Audio has efficient copy protection and can only be played on a DVD-Audio player.
