Interpreting DR scores

Nice job with the 1.3 update. Still trying to understand all the features.

Is there a guide of how to interpret DR scores?

I googled but did not find much info.

You’ll want to refer to this for the hows and whys:

Maybe even the extensive User Guide may be to your liking:

Roon reports Dynamic Range in Loudness Units (LU). 1LU is equivalent to 1dB. The higher the reported LU the greater the dynamic range. Without Program Loudness Dynamic Range doesn’t tell you anything about the average loudness of the program, only how dynamic it is.
