Another crucial piece of the DVD-Audio puzzle fell into place recently when the WG-4 (Working Group 4) DVD-Audio Working Group approved the adoption of MLP (see previous articles <A HREF="http://www.stereophile.com/news/10188/">1</A&gt;, <A HREF="http://www.stereophile.com/news/10200/">2</A&gt;) as the lossless algorithm for DVD-Audio at its August 5th meeting in Tokyo. WG-4 will require official approval from its supervising organizations, the Technical Coordination Group and Steering Committee---considered a formality at this point.

News recently coming out of Cambridge, England promises yet another new revolutionary loudspeaker technology following in the footsteps of <A HREF="http://www.nxt.co.uk/">NXT</A>'s flat-panel speakers and <A HREF="http://www.atcsd.com/">ATC</A>'s <A HREF="http://www.atcsd.com/HTML/whitepaper.html">HyperSonic Sound</A> and <A HREF="http://www.atcsd.com/RELEASES/pr020998.html">Stratified Field Technology</A>. Engineering consultant Tony Hooley heads up a team of researchers who have created what they hope will be a breakthrough in small, lightweight, highly accurate-sounding arrays of digitally driven pressure transducers.

Protection for the creative community or job security for lawyers? These are but two of many interpretations of the <A HREF="http://thomas.loc.gov/cgi-bin/bdquery/z?d105:h.r.02281:">Digital Millennium Copyright Act</A>, which won approval by voice vote in the US House of Representatives August 4. The bill will implement into US law the treaties signed by 157 signatories at the World Intellectual Properties Organization conference in Geneva in December 1996. A separate version was passed by the Senate in May. Differences between the two must be ironed out before a final version can be signed into law by President Clinton.

Some products inspire unwavering loyalty among their owners: Gibson's "Les Paul" Guitars, for example, or Harley-Davidson motorcycles. Only a handful of audio manufacturers have been lucky enough for their products to attain this kind of cult status. McIntosh is perhaps premier among them. Individual products---Audio Research preamps, Marantz tuners, Linn turntables---also have deservedly loyal and sizable followings.

This last year has seen several companies proclaim the launch of the "world's first digital loudspeaker." The term brings to mind some exotic new approach that is neither cone nor ribbon nor electrostat---something as different from all of those as, say, a CD is from a vinyl record or cassette tape.

The Silverdale by the Bay Resort Hotel in Silverdale, WA, will be the site of the second annual Vacuum State of the Art Conference, scheduled for August 21-24.

Frequently a hot topic in the hallowed pages of <I>Stereophile</I>, DVD-Audio will be among the agenda items at the third US DVD Conference on October 1-2, 1998, in San Francisco. Presented by the <A HREF="http://www.dvdforum.org/">DVD Forum</A>, the international association working to develop universal DVD formats, the event will take place at the Grand Peninsula Ballroom at the Hyatt Regency SF Airport.

New companies are springing up all around the web to provide songs for custom CD compilations. (See previous articles <A HREF="http://www.stereophile.com/news/10185/">1</A&gt;, <A HREF="http://www.stereophile.com/news/10157/">2</A&gt;.) You go to the site, choose up to 70 minutes of music from their catalog, and the finished disc is mailed back to you in a couple of days for between 10 and 20 bucks. The challenge for these companies is to have an attractive catalog of artists and songs to choose from.
