The Official DRI /R 128/A85 Measurement App from MAAT runs in the background and automatically measures all mandated R 128 parameters, along with official DRi and a host of key metrics that your DAW may not otherwise display. Much more than just a loudness control for commercials, it provides 24-different measurements, including integrated DRi Dynamic Range and PSR, the emerging Sample Peak-to-Short-Term Loudness Ratio, all measurements that are valuable to a music engineer. This is a cross-platform app that works within your DAW on Windows or Mac.
What is DR?
The DR algorithm, related 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.

Pro Tools and Logic
DROffline MkII offers easy access to all audio statistics and metadata, with an instant drag-and-drop interface. DRO2 works in conjunction with DRMeter MkII to run measurements when you drop an audio file onto a DRM2 instance in your DAW.
