	'''Meridial Lossless Packing''' ('''MLP''') is a [[lossless]] ~~compression scheme~~ developed by the British pro-audio developer and manufacturer Meridian specially for inclusion in the [[DVD-Audio]] format.		'''Meridial Lossless Packing''' ('''MLP''') is a [[lossless]] audio [[codec]] developed by the British pro-audio developer and manufacturer Meridian specially for inclusion in the [[DVD-Audio]] format. The same compression algorithm is applied in [https://en.wikipedia.org/wiki/Dolby_TrueHD Dolby TrueHD] on Blu-Ray discs.

	It's a completely closed format ~~- there is~~ no ~~source code or format documentation available. Also~~, ~~the~~ encoder ~~is quite expensive~~ (US$ 2500 as of October 2005).		It was released as a completely closed format, with no specification, and an expensive encoder (US$ 2500 as of October 2005). It has later been reverse-engineered, and decoding is now [https://www.ffmpeg.org/general.html#Audio-Codecs supported in ffmpeg] (with an experimental encoder).

	~~Compression efficiency is quite bad for~~ CD content (16 bit, 44100 Hz, stereo), being outperformed by [[Shorten]] and even RAR. ~~It is somewhat better~~ for ~~high resolution content~~ (~~multichannel, 24 bit, 96 kHz~~), ~~but still~~ beaten by, ~~e.g.,~~ [[~~WavPack~~]] -~~h in both speed and compression. Compression is very slow~~.		The original encoder was known to be slow, and inefficient on CD content (16 bit, 44100 Hz, stereo), being outperformed by [[Shorten]] and even RAR. MLP supports ''wasted bits'' - marketed as a "feature" for DVD manufacturers to decimate the promised 24 bits to e.g. 22 for compression to lower size. Tested on a DVD with such material (22 effective bits), it was beaten by every other codec that support wasted bits, including [[FLAC]] at its -0 setting.
