Smart Sound Meters Could End Noisy TV Ads


| July 2, 2003


A Canadian company is developing technology that would soften the blast delivered by most TV commercials, reports Kevin Hilton for NewScientist.com. Engineers at International Telecommunication Union?s (ITU) Communications Research Centre are building a new type of software-driven meter that will be tested early this summer, with the results expected to be reported in August. Toning down the often-deafening roar of commercials is more complicated than you might think, Hilton explains, as it involves ?peak loudness limits, average loudness levels, and compressed dynamic ranges.? Still, if ITU engineers are successful, Hilton says, ?The new metering software could be installed in a video server, where it will analyze the programs and ads and adjust the sound in real time as they are broadcast.?
