"So long, farewell, auf Wiedersehen, goodbye." So goes the song. But only some of those sentiments apply to four digital-audio formats that have gone, or are about to depart, from the consumer-electronics scene. DAT, DCC, MD, and SACD never did fare "well" in the marketplace.

06/16/2006 - The news wires have recently been carrying stories on how teens around the world have hijacked a signal in the near-ultrasonic range originally developed by a company in Wales to disperse groups of loitering youth.

Apparently, Dolby isn't satisfied with getting its 7.1-channel Dolby Digital Plus and 8-channel lossless TrueHD technologies into the HD DVD and Blu-ray Disc systems (as requirements in the former, as options in the latter).

03/17/2006 Last weekend I went shopping for a protective jacket for the iPod Nano I bought recently. (Yes, even Sound & Vision reviewers buy gear at retail.) The buzz was that the Nano's high-gloss finish was more easily scratched than the finish on earlier iPods, something I can't verify.
