Editing Lossless Transform Audio Compression

'''Lossless Transform Audio Compression''' ('''LTAC''') is a [[audio data compression|compression]] algorithm developed by [[Tilman Liebchen]], [[Marcus Purat]] and [[Peter Noll]] at Institute for Telecommunications, [[Technische Universität Berlin]] ([[TU Berlin]]),<ref name=gibson2002/> to compress [[Pulse-code modulation|PCM]] audio in a [[lossless compression|lossless]] manner, ''unlike'' conventional [[lossy compression|lossy]] [[audio data compression|audio compression]] algorithms (like [[MP3]]).

LTAC will not be developed any further since it has been superseded by its successor [[lossless predictive audio compression]] (LPAC), which is based on [[linear prediction]].<ref name=whittle/> This makes it much faster than LTAC and even leads to better compression results. LPAC has become official standard as MPEG-4 [[Audio Lossless Coding]].
