LATEST ADDITIONS

A much-touted benefit of DVD-Audio and Super Audio CD is that these new media can store digital audio data extending one or more octaves higher in frequency response than the capabilities of the CD. In the August issue's "Industry Update" (pp.27-29), Paul Messenger reported on an add-on supertweeter from English manufacturer Tannoy that would extend the ultrasonic response of loudspeakers so they can reproduce this new information. Putting to one side for now the issue of whether a loudspeaker really needs to be able to reproduce frequencies that no one can hear, the subject of how much ultrasonic content is present in real musical signals is still a contentious one.

I've long been a fan of Naim electronic gear, and have used it for many years. I also have admiration and respect for the company's uncompromisingly consistent and determinedly individualistic approach to the various tasks and problems of loudspeaker design. But my enthusiasm for Naim speakers has long been tempered by a feeling that mechanical aspects of the design are given priority over acoustics and styling.

With multichannel DVD-Audio and SACD discs close to reality, record companies can encode their discs in a variety of multichannel formats (see recent <A HREF="http://www.stereophile.com/shownews.cgi?849">Chesky interview</A>). Any preferences?

The online music world has been hit by one jolt after another as the record labels go after anyone they can slap with the "music pirate" label. In response, the e-sharks smell blood and are circling. Internet music-distribution company <A HREF="http://www.EMusic.com">EMusic</A&gt; sent out a press release recently making the assertion that "now that Napster and MP3.com are both on shaky legal ground, many downloadable-music fans are going to be looking for compelling, 'legitimate' alternatives."

It may still be a trickle, but at least a little music relief has reached the parched throats of audiophiles awaiting the arrival of DVD-Audio discs. Last week saw the <A HREF="http://www.stereophile.com/news/10867/">announcement</A&gt; that Aaron Neville's latest CD release will also hit stores as a multichannel DVD-A on Immergent Records on October 24. This week sees the announcement that another recording legend, Willie Nelson, will soon take the plunge.

John Atkinson shuffles his feet a little and finally mutters, " . . . Convergence." He laments, "I swore I wasn't going to use the 'C' word, but when you're faced with writing about a product that smashes the boundaries between component categories as completely as the CardDeluxe does, you have little choice." JA reviews the <A HREF="http://www.stereophile.com//digitalsourcereviews/280/">Digital Audio Labs CardDeluxe PC soundcard</A> and answers the pointed question: "But it's only a PC soundcard. What's the big deal?"

With $60,000 in award money as incentive, the hacker community is helping the <A HREF="http://www.sdmi.org/">Secure Digital Music Initiative</A> find out just how secure six proposed watermarking technologies really are. On October 12, as SDMI representatives were <A HREF="http://www.stereophile.com/news/10870/">testing</A&gt; the audibility of three of the watermarks, the organization announced the closure of a month-long challenge it had offered hackers: break the code. According to the terms of the challenge, each defeated technology will mean $10,000 to a successful hacker.
