New Dialogue Intelligence Feature Dramatically Simplifies Use of Dolby's Loudness Meter
Apr 2, 2003
Dialogue Intelligence automatically quantifies program loudness
"Everyone is annoyed by different volume levels while changing TV channels. We expect the LM100, with this new functionality, to be instrumental in addressing and regulating this issue of loudness," said Tom Daily, Marketing Director, Professional Audio, Dolby Laboratories. "Dialogue Intelligence makes this product simple to use. It measures the loudness of a program and presents the broadcaster with one single, easyto- understand numeric loudness value," he continued.
Proper use of this product will help identify where in the broadcasting chain adjustments to program volume should be made. The LM100 Loudness Meter is also capable of logging loudness history and several other user-defined alarm conditions to assist operations personnel when problems arise.
The LM100 accepts and measures both two-channel PCM and stereo analog (baseband) audio, as well as multichannel Dolby® Digital and Dolby E encoded streams. One version, the LM100-NTSC, measures in-the-clear analog CATV and off-air NTSC RF signals for cable television facilities. The LM100-LTC version has a time code input for those facilities that want to reference the log to time code. LM100 applications include postproduction, cable head-end, direct broadcast satellite, network origination centers, and turnaround uplinks.
