Those Fraunhofer folks are nothing if not prolific, and it now looks like they're getting a little boastful as well, as evidenced by some comments reps from the group made at CES this week. As MacWorld reports, Fraunhofer IIS is not only saying that its new HD-ACC codec is "better than CD," but that it "makes CDs obsolete." That is apparently due to the codec's lossless compression of 24-bit music content, as opposed to the 16-bit, 44.1 kHz quality now found on CDs. What's more, the HD-AAC encoding process embeds a so-called "core layer" on any device that supports plain old AACs, although you'll obviously need a player with an HD-AAC decoder in order to take advantage of the fully lossless signal. Of course, some formats have a tendency to take off more quickly than others, so we'll just have to wait and see how HD-ACC plays out in the grander scheme of things.
