Dolby® Media Meter 2, like the original Dolby Media Meter software tool, accurately and objectively measures loudness as viewers subjectively experience it. New features include user-selectable measurement algorithms and a high-quality peak limiter. It is available as an inclusive package or as an update to the original version.

As a stand-alone product or a Digidesign AudioSuite plug-in, Dolby Media Meter 2 is a faster-than-real-time, file-based measurement application.1 This is useful for DVD and Blu-ray Disc™ mastering, and for program creation and quality control applications in audio production, postproduction, and broadcast facilities. As a Pro Tools RTAS or VST plug-in, Dolby Media Meter 2 measures loudness in real time, so that users can track levels during the mixing process to help meet network delivery requirements. Real-time versions can simultaneously display short- and long-term loudness levels with or without Dialogue Intelligence.

Differences in audio levels between programs and channels or between programs and commercials are a major annoyance to TV viewers. While obvious to the viewer, these loudness differences have proven difficult to measure with conventional methods and equipment.

With Dolby Media Meter, Dolby adds to its lineup of unique and innovative tools that accurately and objectively measure loudness as viewers subjectively experience it. Dolby Media Meter features Dialogue Intelligence technology, adopted from the award-winning Dolby DP600 Program Optimizer, that automatically detects and then measures loudness only during the presence of speech in an audio track. Dolby Media Meter measures loudness using the ITU-R BS.1770-1 algorithm, and measurements can be done either with or without Dialogue Intelligence.

Dolby Media Meter runs as a Mac or Windows stand-alone application, as a Digidesign Pro Tools AudioSuite or RTAS plug-in, and as a plug-in for Minnetonka AudioTools AWE. Dolby Media Meter supports measurement of Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby E, and PCM audio formats. All versions of Dolby Media Meter can produce and save log files.

Used as a stand-alone product, Digidesign AudioSuite plug-in, and Minnetonka AudioTools AWE plug-in, Dolby Media Meter is a faster-than-real-time, file-based measurement application. This is useful for DVD and Blu-ray Disc mastering, and for program creation and quality control applications in audio production, postproduction, and broadcast facilities.

As a Pro Tools RTAS plug-in, Dolby Media Meter measures loudness in real time, so that users can track levels during the mixing process to help meet network delivery requirements. The RTAS plug-in can simultaneously display short- and long-term loudness levels that are based on the level of dialogue in the mix.

Speed will depend on hardware capabilities.
