There is the original tool from the PMF (TT DR Offline Meter) that can only read PCM WAV files. It's free.
There is a compatible foobar2000 component, which creates compatible log files and works with all file formats that foobar2000 can read. This is also free.
Both use the original older DR measuring algorithm and aren't actively developed any more.
And there is MAAT DROffline and its more potent version MkII. Both are commercial but are actively developed and use a newer more precise measuring algorithm. MAAT DROffline is the official successor of the old TT DR Offline Meter.
