Lossless Transform Audio Compression (LTAC)

From Free net encyclopedia

Lossless Transform Audio Compression (LTAC) is a compression algorithm developed by Tilman Liebchen, Marcus Purat and Peter Noll at Institute for Telecommunications, Technical University Berlin (TU Berlin), to compress PCM audio in a lossless manner, unlike conventional lossy audio compression algorithms (like MP3).

Meanwhile there is Lossless Predictive Audio Compression (LPAC), which is based on linear prediction. This makes it much faster than LTAC and even leads to better compression results. LTAC will not be developed any further.
