Lossless Transform Audio Compression

from Wikipedia, the free encyclopedia

Lossless Transform Audio Compression ( LTAC ; German: lossless transformation audio data compression ) is a historical, lossless method for audio compression, developed by Tilman Liebchen, Marcus Purat and Peter Noll from the messaging department of the Technical University of Berlin .

LTAC is the forerunner of Lossless Predictive Audio Compression (LPAC). This procedure has been standardized since December 2005 in a further developed form as MPEG-4 Audio Lossless Coding . The procedure has only been open since standardization.
