If a DVD-Audio player's decryption key is compromised, that key can be rendered useless for decrypting future DVD-Audio discs. The player must use its own unique key to decrypt the MKB. In order to decrypt the audio, players must obtain a media key from the MKB, which also is encrypted. The encryption is called Content Protection for Prerecorded Media (CPPM), which uses a media key block (MKB) to authenticate DVD-Audio players. More information can be found here.ĭVD-Audio streams can be encrypted. There is also audio present in the VIDEO_TS folder, but of lower quality (that is with a lower sample rate and a lower bit depth). Usually, a DVD-Audio contains 5.1ch MLP / 2.0ch MLP or 5.1ch MLP / 2.0ch LPCM. The audio in the AUDIO_TS folder can be either Linear Pulse Code Modulation (abbreviated LPCM, which is uncompressed) or Meridian Lossless Packing (abbreviated MLP, which is losslessly compressed). A DVD-Audio contains both DVD-Audio content (in the AUDIO_TS folder) and DVD-Video content (in the VIDEO_TS folder) and has the DVD-Audio logo. Supported sample rates range from 44.1KHz up to 192KHz, with bit depths of 16, 20 or 24 bits. 3.4.2.3 using AviSynth input plugin for Foobar2000 v0.9 (MLP and LPCM)ĭVD-Audio is a standard for storing high quality stereo or multi-channel audio content on a standard DVD disk.3.4.2.1 using FLAC 1.2.0 and the SoundOut AviSynth plugin (MLP).3.3 Demuxing (audio streams, MLP or LPCM, from.
