The Minnetonka Audio Dolby Media Meter 2 Software is designed to measure loudness in program material for media, broadcast, cinema trailers, games, and VOD. Industry standards require that the audio levels of program material fall within defined ranges, which in turn requires tools that can accurately measure loudness. The software is adapted from the Dolby DP600 Program Optimizer and complies with ITU-R BS.1770 and EBU R-128 loudness measurement specifications.
The software includes a dialogue intelligence feature which automatically detects speech in audio and measures loudness where dialogue occurs. You can also select different ways of measuring loudness depending upon the application, such as true peak, Leq(A), and Leq(m) for commercials and movie trailers. The software features real-time graphing, level meters, a user-selectable peak limiter, and warning settings for when loudness exceeds a user-defined threshold.
The software runs as a stand-alone application on both Mac and Windows and as a plug-in with Pro Tools AudioSuite, Pro Tools RTAS, VST, and AU on Mac. All of these versions of the software can generate a log file for the loudness measurements. The stand-alone version can process audio faster than real-time depending upon hardware requirements, which is useful when mastering optical media and in broadcast, production, and postproduction quality control applications. As a plug-in, the software can simultaneously display long-term and short-term loudness levels while mixing. The software supports Dolby E, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, and PCM file formats.
