'''Lossless Predictivepredictive Audioaudio Compressioncompression''' ('''LPAC)''') is an improved [[lossless compression|lossless]] [[audio data compression|audio compression]] algorithm developed by [[Tilman Liebchen]], [[Marcus Purat]] and [[Peter Noll]] at the Institute for Telecommunications, [[Technische Universität Berlin]] (TU Berlin),<ref>{{cite web | url=http://www.nue.tu-berlin.de/index_e.html Institute| forarchive-url=https://web.archive.org/web/20030814010851/http://www.nue.tu-berlin.de/index_e.html Telecommunications],| Technicalarchive-date=2003-08-14 University| [[Berlin]]title=Nachrichtenübertragung - ([[TU Berlin]]), }}</ref> to compress [[PCM audio]] in a [[lossless compression|lossless]] manner, ''unlike''in conventionalcontrast [[audio compression]] algorithms which areto [[lossy compression|lossy]] algorithms.

Meanwhile itIt is no longer developed because an advanced version of it has become an official standard under the name of MPEG-4 [[Audio Lossless Coding]].
