Did an iPod Scuttle the Flag?

As we reported last">http://www.stereophile.com/news/012306fairuse/">last week, the Senate Commerce Committee (SCC) held hearings on January 24 exploring regulations to insert "Broadcast Flags" and "Audio Flags" into broadcast signals and audio recordings—markers that would prevent electronic devices from recording the flagged material. What we did not anticipate last week was that the hearings would trigger an outpouring of common sense.

Dieter Burmester founded Burmester Audiosysteme GmbH in 1977 and ran it for 38 years. For me, he was the friendly face of an unusually friendly and outgoing German high-end hi-fi company. He died on August 15, and his company will badly miss him.

Digital Airwaves Arrive

Those unhappy with today's over-the-air broadcasting choices will be glad to know that this is shaping up as a busy year for new radio formats. The commercialization of the IBOC AM and FM digital broadcasting system is about to be revealed at the same time that Sirius satellite radio announces that it will be accelerating its rollout schedule in an effort to compete with rival XM satellite radio.

Digital Audio Amplification Reaching Critical Mass?

Although it first appeared as an infant technology more than 20 years ago, digital audio amplification may finally be coming of age. Recent months have seen announcements from several companies, including news of Apogee's DDX technology (see previous">http://www.stereophile.com/news/10893/">previous report) and Cirrus Logic who recently purchased their Pulse Width Modulation (PWM) digital amplification technology from B&W Loudspeakers (see previous">http://www.stereophile.com/news/10866/">previous report).

Digital Audio Forges Ahead

Analog audio electronics are approaching "maturity," a state eventually achieved by most technologies, in which almost all the great discoveries have been made and progress becomes a process of increasingly arcane refinements. Digital audio is in no such danger, as evidenced by three new product announcements made the first week of April.

Digital Audio MaGIC

In the crush of new products and technologies scrambling for attention at every Consumer Electronics Show, some intriguing announcements can get buried in the noise and require a closer look than is afforded by a quick listen and chat in a demo room. One such technology on display at the 2002 CES was MaGIChttp://www.gibsonmagic.com">MaGIC;, a new high-resolution audio connectivity standard.

Digital Audio Watermark Watch

In the perfect digital future, audiophiles would be able to drink from the purest of high-resolution audio datastreams with no worry that someone upstream had polluted the current. But in the real world, content providers and hardware manufacturers increasingly conspire to dirty the flow a little and limit unauthorized consumption by controlling the technology needed to filter out their toxic additives.
