Supreme Court Tackles P2P

Long-simmering disputes about peer-to-peer file sharing, or P2P, will finally come to a boil sometime next year. On Friday, December 10, the US Supreme Court agreed to examine whether online services Grokster Ltd. and StreamCast Networks, Inc. are liable for copyright infringement. Both services enable users to share music and other forms of copyrighted material, and both derive revenue from advertising.

Auto Surround

A local body shop owner explained to me recently how the center brake light that began showing up on the rear deck of cars a few years ago killed business for him and his pals. Seems that all of a sudden, folks weren't rear-ending each other as often.

Satellite Radio and Toyota

The future is still bright for satellite radio. On December 8, XM Satellite Radio Holdings, Inc. announced that it had signed a deal with Toyota Motor Corporation to begin factory-level installation of XM receivers in 2006. The most popular brand of automobile in the world, Toyota is the last large automaker to commit to either XM or its competitor, Sirius Satellite Radio.

The Digital Genie's Out of the Bottle

In early 2000, the British magazine <I>The Economist</I> published a lead editorial addressing America Online's acquisition of media giant Time Warner. In the editors' view, TW was a clunky, old-style media company that needed a fresh injection of dot-com blood to help them reach a more narrowly targeted audience. "Sex, shopping and violence," the editors wrote, echoing Internet visionary George Gilder, "...are what people have in common. What differentiates them is their enthusiasm for folk music, tropical fish, or Viennese waltzes."

Revel Ultima Sub 30 powered subwoofer

It didn't seem like such a big deal. After all, when designer Kevin Voecks added a passive radiator to the bottom of Revel Loudspeakers' powerful <A HREF="http://www.stereophile.com/loudspeakerreviews/90">Ultima Sub 15</A> subwoofer, no one expected that the resulting 6dB increase in bass output below 35Hz would be so audible. However, Revel's sophisticated double-blind listening tests (described in my review of their flagship <A HREF="http://www.stereophile.com/loudspeakerreviews/96">Ultima Salon</A> full-range loudspeaker in the March 1999 <I>Stereophile</I>, revealed that a big change had occurred. With now twice the radiating surface, the modified Sub 15 produced significantly deeper, more powerful bass.

Ambisonic Revival

All but forgotten in the field of surround sound are the efforts of UK classical music label <A HREF="http://www.wyastone.co.uk">Nimbus Records</A>. More than 25 years ago, Nimbus recorded with Peter Fellgett and Michael Gerzon's two-channel&ndash;compatible, matrixed UHJ Ambisonic Surround system, using multi-capsule Calrec Soundfield microphones. Other labels, including Unicorn-Kanchana, also supported Ambisonic, releasing such rarities as a UHJ Ambisonic recording of the soundtrack to <I>North By Northwest</I> on LP. Playback decoders were available from the UK's National Research and Development Council (NRDC) and speaker manufacturer IMF. As timing would have it, the Ambisonic releases appeared when users could still recall the unfortunate experience of 1970s quadraphony, and Dolby Digital was still some years off. However, those who have heard proper demonstrations maintain that the UHJ Ambisonic technique remains the most convincing surround-sound format ever.
