As expected, the DVD WG-4 Audio Working Group announced at CES that it has released a draft of its DVD-Audio specification to the 10 original DVD consortium companies, and to music-industry associations RIAA (Recording Industry Association of America), RIAJ (Recording Industry Association of Japan), and IFPI (International Federation of the Phonographic Industry).

In a press conference held January 9 at the 1998 Winter Consumer Electronics Show in Las Vegas, Classic Records announced the debut of the Classic 24/96 digital audio disc "DAD" series of audio-only DVD-Videos. (Video information is included on the disc but represents only a tiny fraction of the data space.)

A continuing proliferation of formats is as likely in the audio realm as it is in video. The analog cassette was one of the most successful formats in history, and the industry has yet to find a replacement for it. MiniDisc, a Sony-originated format, required several attempts to introduce it to the American market.

The Academy Advancing High Performance Audio & Video (formerly the Academy for the Advancement of High End Audio) kicked off CES '98 with a pre-Show meeting. Meridian's Bob Stuart addressed the thorny issue of competing and (as yet) not fully defined standards for DVD-Audio.

The one Wes used was originally intended for construction work, not tweaking one's speaker placement, but now there's one available specifically for that purpose: The 770 SA-S Laser Sound Alignment System by Checkpoint Laser Tools.

For years, there has been concern in the high-end audio press about the effects of jitter on digital audio. Manufacturers spend countless design hours measuring jitter and trying to minimize its influence on the sound of their products.
