Lossless Predictive Audio Compression (LPAC) is an improved lossless audio 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 it is no longer developed because an advanced version of it has become an official standard under the name of MPEG-4 Audio Lossless Coding.
