Merdian Lossless Packing (MLP)

Meridian's Lossless Packing (MLP) is the main technology behind DVD-Audio. Its lossless compression scheme was groundbreaking and competed favorably with Sony's DSD technology found in the SACD format. MLP is capable of reproducing a master-quality audio presentation in stereo or in 5.1 surround sound from a DVD-Audio disc and a number of other formats. MLP is a music-friendly compression format that helps get more data onto discs of many varieties.

While not used as much now, given the near-demise of the DVD-Audio format, MLP lives on as a major component of Dolby TrueHD.

Lossless compression is works in a similar fashion as "Zip" files on a computer, where the data is compressed, but not of it lost. So when it is unpacked, all the original data can be recovered. Generally, MLP provides a 2:1 level of compression.

This is the opposite of "lossy" compression (like MP3), in which data is left out, and can never be recovered.
