Microsoft licensing -- unbelievable!

Today Microsoft announced that they will license some of their "unused" intellectual property (IP) to other companies. The AP wire report mentioned "computer tricks that make chintzy speakers sound top-notch". Curious, I went to the Microsoft licensing website to investigate (linked below).

They describe DSP algorithms to compensate for the deficiencies of loudspeakers. Who are these guys kidding? These techniques are widely known, used, and available. Next thing they'll probably try to license electricity...
