'''Lossless predictive audio compression (LPAC)''' is an improved [[lossless compression|lossless]] [[audio data compression|audio compression]] algorithm developed by [[Tilman Liebchen]], [[Marcus Purat]] and [[Peter Noll]] at [https://web.archive.org/web/20030814010851/http://www.nue.tu-berlin.de/index_e.html Institute for Telecommunications], Technical University [[Berlin]] ([[TU Berlin]]), to compress PCM audio in a [[lossless compression|lossless]] manner, ''unlike'' conventional audio compression algorithms which are [[lossy compression|lossy]].
Meanwhile, it is no longer developed because an advanced version of it has become an official standard under the name of MPEG-4 [[Audio Lossless Coding]].
