Might be useful for a widely-compatible lossy/lossless hybrid. I wonder if they've done something clever - when I tried this years ago, mp3 was a terrible base for lossless coding - the lossy>lossless "correction" file was often larger than a straight lossless encode. Maybe this new technology is more tightly integrated into mp3, so performs better? Cheers, David. This post has been edited by 2Bdecided: Mar 19 2009, 17:36
