Dolby Media Meter Software

Dolby Media Meter Software

Dolby® Media Meter is a software tool that measures loudness in programming for broadcast, packaged media, cinema trailers, video on demand (VOD), and games.

Differences in audio levels between programs and channels or between programs and commercials cause major annoyances to TV viewers. These differences have proven much easier to hear than to measure.

Dolby Media Meter joins the lineup of unique and innovative Dolby tools that solve the measurement problems, accurately and objectively measuring loudness as viewers subjectively experience it.

Dolby Media Meter features Dialogue Intelligence™ technology, adapted from the award-winning Dolby Program Optimizer DP600. Dialogue Intelligence automatically detects speech in the audio track and only then measures loudness.

As its core measurement option, Dolby Media Meter uses the ITU-R BS.1770-1, BS-1770-2, or BS-1770-3 algorithms. Measurements can be done with or without Dialogue Intelligence. Dolby Media Meter includes all the measurements required for EBU R128 mode operation.

Other user-selectable measurement options include:

Leq(m) for cinema trailers and commercials


True Peak

Dialogue Range

Loudness Range

Dolby Media Meter adds a number of features to the original Dolby Media Meter, including:

Level meters

A high-quality, user-selectable peak limiter

A warning setting with user-selectable function and threshold

Real-time graphing

For accuracy, flexibility, and ease of use, Dolby Media Meter delivers an unbeatable value. A paid upgrade is also available for owners of the original Dolby Media Meter.

Dolby Media Meter runs as an Apple® Macintosh® or a Microsoft® Windows® stand-alone application and as a plug-in for the following platforms:

Avid® Pro Tools® AAX

Avid Pro Tools AudioSuite


All versions can produce and save log files.

Used as a stand-alone product or an AudioSuite plug-in, Dolby Media Meter offers faster-than-real-time, file-based measurement (speed is hardware-dependent). 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 an AAX plug-in for Avid Pro Tools, or as a VST plug-in for applications such as Steinberg® Nuendo® or Sony® Sound Forge™, Dolby Media Meter measures loudness in real time, allowing you to 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.

Supported audio formats include:

Dolby Digital

Dolby Digital Plus™

Dolby TrueHD

Dolby E
