GenAudio astounded me at last year's CES with its AstoundSound 3D audio system, which creates a convincing spherical soundfield from two speakers. This year, the company announced that its launching AstoundSound for CE, an application that manufacturers can include in their products, such as iPod speakers, soundbars, and TVs—in fact, GenAudio is partnering with Analog Devices and other DSP makers to include the algorithm in their chips.

I heard a clip from Kitaro's Earth in Bloom that was downmixed from 5.1 to 2 channels and then expanded by AstoundSound in real time played first on a $12,000 pair of Gheithain pro studio monitors and then on a $300 2.1 Panasonic soundbar, and the result was remarkable, with various sounds flying all around the room, including overhead. Of course, the studio monitors had better sound quality, but the effect was quite pronounced—and enjoyable—from both.

As I'm sure most <I>UAV</I> readers know by now, analog-television broadcasting will cease on February 17, 2009, less than a year from now. On that date, all analog TVs receiving their signals via over-the-air antennas will display nothing but snow on every channel. Cable and satellite delivery to analog TVs will be unaffected&mdash;in fact, the Federal Communications Commission (FCC) has mandated that cable companies continue to provide analog services until at least 2012. But that still leaves some 14 million US homes in the dark on that fateful day next year.

Robert is just getting started in the whole home-theater game, and he has some basic questions:

The materials used to make speaker diaphragms are well established&#151;polypropylene, paper, Kevlar, aluminum, titanium, beryllium, silk, and even diamond, to name a few. So I was surprised to find a speaker system with diaphragms made of glass. Developed over nearly four years by a Japanese glass company called <A href="http://www.harioglass.com">Hario</A> (Japanese for "king of glass"), the Harion system is certainly intriguing, though the English-language website linked here has nothing about it, and the company did not supply much info, even after repeated requests.
