Lossless compression provides bit-exact delivery of the original signal and is ideal where the highest possible confidence in the final sound quality is required. Meridian Lossless Packing (MLP) has recently been adopted as the lossless coding method used on DVD-Audio. MLP uses four principal strategies to reduce both the total quantity and the peak rate of encoded data. MLP can invert a matrix transformation losslessly, allowing a two-channel representation to be transmitted alongside a multichannel signal, with minimal increase in data rate. The paper illustrates how the characteristics of the incoming audio affect the coding performance and indicates MLP's versatility achieved by the use of substreams and an open-ended metadata specification.
