Embedding Data Signals In White Noise

Posted by timothy on from the literally-subliminal dept.

Anemophilous Coward writes "ZDNet has the following article which describes a company that 'has devised a method for sending wireless signals over ordinary audio speakers so that humans can't hear them. With this same technology, radio stations can unobtrusively transmit ads, Web site URLs, or information about music and artists to in-car cell phones.'" Here is some further reading about the company, Intrasonics.

    Oh sure, first you guys complain about MICROSOFT articles, then articles on non-free SOFTWARE, now some company MAKES a speaker whose only purpose is to control YOU, and you're HAPPY to praise it. But remember, every time you BUY a set of these speakers, MICROSOFT gets more money so they can create more of their crappy SOFTWARE. If you want to be free, stick with LINUX. Free software IS the answer, and using Microsoft is more like slavery or COMMUNISM.
