Gourt Home::Gourt :: Meridian Lossless Packing
Meridian Lossless Packing is a proprietary lossless compression technique for compressing PCM audio data developed by Meridian Audio, Ltd. MLP is the standard lossless compression method for DVD-Audio content (often advertised with the Advanced Resolution logo) and typically provides about 2:1 compression on most music material. All DVD-Audio players are equipped with MLP decoding, while its use on the discs themselves is at their producers' discretion.
It is also known as Packed PCM (PPCM) and with the next generation of DVDs will be known as Dolby TrueHD, adding higher sample rates, higher bit rates, 8 full-range channels, extensive metadata, custom speaker placements (as specified by SMPTE), and timecode.
