Bill Gates would have you believe we live in a plug'n'play world. Apple has proselytized same since day one. But I'm here to tell you it just isn't so for high-end audio. The orientation of a component's AC plug—even the quality of the wall receptacle itself—affects the sound! Oh no, Mr. Bill, not something else to futz with! Will it never end?

A study released earlier this month by <A HREF="http://www.arbitron.com">The Arbitron Company</A> and <A HREF="http://www.edisonresearch.com">Edison Media Research</A> shows that Internet radio broadcasting continues to be a fast-growing medium. The survey of Arbitron diarykeepers also brings to light both the challenges and opportunities that the Internet presents to radio broadcasters, particularly in the much-talked-about arena of e-commerce.

In the classic textbook example, the Doppler effect is demonstrated by an increase in both pitch and volume (or amplitude) of a train's whistle as it approaches a station, followed by a decrease in pitch and volume as it moves away. This effect---the shift of a frequency emitted by a moving object---leads to a fundamental flaw in audio technology. A midrange driver behaves like the approaching-and-departing train when it attempts to reproduce varying frequencies. When the driver is fed simultaneous 400Hz and 2kHz tones, the forward movement of the cone at the lower rate modulates the 2kHz tone upward in pitch and amplitude; when it moves backward it modulates the higher tone downward. (The human eardrum also behaves this way, but the brain's audio-analysis circuitry knows how to deal with it.)

Two elements that keep the audio business interesting are the new companies and technologies arriving almost every week (see also BW's <A HREF="http://www.stereophile.com/news/10382/">story</A&gt;). Some stick around for years, while others fade away between hi-fi shows. But amid the incessant change are a handful of characters who stay with it, continually evolving with the industry and reinventing themselves with each twist and turn.

The official <A HREF="http://www.grammy.com/">website</A&gt; of the 41st Annual Grammy Awards was launched earlier this month with the help of a media team from the Atlanta division of <A HREF="http://www.ibm.com/">International Business Machines</A>. The Java-based site provides background information on the artists and events of the music-awards extravaganza, taking place Wednesday evening, February 24, at the Shrine Auditorium in Los Angeles.

You think we've got format problems these days? Take a peek back to 1963, when J. Gordon Holt ripped apart the then-new record technology from RCA in <A HREF="http://www.stereophile.com//asweseeit/95/">"Down with Dynagroove"</A>. Next, Wes Phillips writes an ode to his own Mr. Holland in <A HREF="http://www.stereophile.com//asweseeit/94/">"A Passion for Music"</A>.

Because online music retailers like <A HREF="http://www.cdnow.com">CDNow</A&gt; and <A HREF="http://www.Amazon.com">Amazon.com</A&gt; have likely taken a bite out of record-club sales, last week Internet company <A HREF="http://www.aol.com">America Online</A> and direct music marketer <A HREF="http://www.columbiahouse.com">Columbia House</A> announced a marketing agreement for both online and offline advertising and promotions, including product bundling, direct-mail initiatives, and co-marketing and advertising campaigns. Under the multi-year agreement, Columbia House, with more than 13 million members, will promote its music, video, and DVD clubs on AOL's Shopping Channel, as well as on AOL.com, CompuServe, Digital City, and Entertainment Asylum.

After dozens of thorny issues slowed its progress (see <A HREF="http://www.stereophile.com/news/10281/">previous report</A>), last week the <A HREF="http://www.dvdforum.com/">DVD Forum</A> announced that its Steering Committee has approved Version 1.0 of the DVD-Audio Disc specifications, making it the fifth of the DVD format family after DVD-Video, DVD-ROM, DVD-RAM, and DVD-R. According to a statement, the DVD Forum says it will soon publish the DVD-Audio Format Book, which contains the detailed specification of the format, and make it available to authorized companies by "early spring of this year."
