A measurement app that analyses single audio files or entire folders in the background, determining all values mandated by R 128 and A/85 as well as the official DRi dynamic range value.

DROffline MkII provides 24 different measurements, including integrated DRi dynamic range, ITU loudness values, true peak and PSR, the sample-peak-to-short-term-loudness ratio. While you carry on working, it creates plain-text and tab-delimited logs, optionally with engineer and studio metadata, which serve as client reports for replication and distribution or as documentation. Files can be measured by drag and drop, including via a DRMeter MkII instance in your DAW, and the DR method shows how much dynamic range a mix has lost to compression and limiting.
