Truly the Only Way to Measure DR

MAAT’s DROffline batch measurement app is the only software that generates official DR readings. Offering essential options for musically justified, file–based metering, DROffline includes DR dynamic range, SPPM Peak and RMS amplitude. One file can be evaluated, or an entire directory can be measured in batch mode.

What is DR?

The DR algorithm, akin to PLR (Peak–to–Loudness Ratio) or “crest factor,” specifically measures the dynamic density or lack of dynamics caused by overly aggressive dynamic compression and limiting. Although the companion DRMeter provides an estimate of the "official" DR Value, only the DROffline utility can generate official values, which are cumulative over the entire length of a song. Only DROffline can scrub through an entire song or track, resulting in an official DR number.
The complete DR metering system, composed of the realtime DRMeter plus the DROffline batch processor, was created by Friedemann Tischmeyer to address the need to generate a repeatable, easy to understand numeric value. Seeing a meaningful and easy to understand indication of dynamic range inspires users to back away from hyper compression.

Buy It & Help Us Grow

As an introduction to everyone in the audio community, we’re offering this rather useful utility at a very reasonable price. Thanks for visiting, and stay tuned for the upcoming, upgradable DRMeterMkII, which features all modern metering algorithms, including True Peak Level and Loudness Units compliant with EBU R128 and ATSC A/85. We hope to be working with you more in the future, drop by often to see what’s new!

Not Only The Doctor Has a Companion

The MAAT DROffline release is MAAT’s second step in bringing forward the legacy of the PMF’s legendary TT Dynamic Range metering system, which was certainly the most popular metering plug—in of the last decade. DROffline has be modernized to work with current version of Windows and macOS operating systems.
The companion DRMeter is a plug-in that generates approximate DR values when applied to the loudest passages in a track. Due to its realtime operation, it cannot measure official DR values, but it can estimate DR while you work. To download your copy of DRMeter, head over to ... DRMeter
