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 audio compression algorithms which are lossy.

Meanwhile there is 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 developped any further.
