Another Audio Watermark Scheme Wins TI DSP Contest

CaptainTylor writes: "Texas Instruments' DSP and Analog Design Contest Challenge is over, and the winner is a group of students from Technion, the Israel Institute of Technology, who presented yet another scheme for digital-audio watermarking, and got US$100,000 for it. Here is a Dallas Morning News article on the winners, which is of course light on the tech details. Abstracts of the winner and the other two finalists are available, but I couldn't find the full submissions. It's worth noting that the competition was not specifically about copyright protection, just about using the TI TMS320 DSP in interesting ways. Wonder how long it'll take before someone cracks this scheme..."

And speaking of schemes, cracking, audio and contests, Logic Bomb writes: "According to an article from the Associated Press, the United States National Archives are holding a contest of sorts to see if anyone can finally figure out what was erased on the infamous Watergate tape that pushed Nixon's downfall over the brink. It would be amazing to have this national mystery put to rest."

So, monkey-boy, what you are saying is that the digital watermark will stay along with the Analog sound signal in the air? After it leaves a speaker?

If that is the case, I would imagine that you would hear this watermark, thus making the creation of a watermark a waste of time. Since, nobody wants to buy music that is very poorly recorded with a screeching sound over it.]

Perhaps you should read a little about physics and the reproduction of sound waves.
