Dynamic Range differences between Roon and Foobar Dynamic Range Meter V1.1.1

Then there’s the first 80s press of Van Halen II; Roon shows DR 7, JRiver more accurately shows an average of DR 12, which generally correct for non-remastered album of the 80’s. In these cases, it would mean the first press of Van Halen is louder than newer c…
