IFA 2007: Dolby Volume Technology

Aug 31 2007, 2:10am CDT | by Luigi Lugmayr

Dolby Laboratories demonstrated Dolby Volume technology for home audio systems, including audio/video receivers (AVRs), home-theater-in-a-box systems, and stereo audio systems at the IFA 2007 in Berlin.

First announced at 2007 International CES, Dolby Volume brings a fundamentally new approach to delivering consistent volume levels across a wide variety of channel programming or input sources. This unique technology performs measurement, analysis, and control of volume levels according to a psychoacoustic model based on the characteristics of human hearing. Dolby Volume complements Dolby Digital (AC-3), the de facto standard for surround sound in DVB-based broadcasting, as well as the audio standard for DVD-Video and for DTV broadcasting in North America. Together they provide a comprehensive solution for controlling loudness over a wide range of consumer media formats.
Dolby Digital as implemented in digital broadcast, DVD, and next-generation high-definition optical media contains a mechanism for controlling loudness through the digital broadcast chain by the use of audio metadata, specifically the dialogue normalization parameter, which indicates the average program loudness.

At IFA, Dolby also demonstrated growing industry support and momentum for its next-generation technologies Dolby Digital Plus and Dolby TrueHD.
