'''MPEG-1 Audio Layer III HD''', more commonly known and advertised by its abbreviation '''mp3HD''', is an audio compression [[codec]] developed by Technicolor formerly known as Thomson.<ref>[http://crave.cnet.co.uk/digitalmusic/mp3hd-new-lossless-mp3-format-explained-49301678/ mp3HD: New lossless MP3 format explained]</ref> It achieves [[lossless]] data compression, and is backwards compatible with the [[MP3]] format by storing two data streams in one file.<ref>[https://arstechnica.com/information-technology/2009/03/new-lossless-mp3hd-format-trades-convenience-for-file-size/ New lossless mp3HD format trades convenience for file size | Ars Technica]</ref>

As of April 2013, the mp3HD website, specification and encoder software are no longer available, and promotion of the format appears to have been abandoned.
