Dynamic range measurement is different than http://dr.loudness-war.info

No, it’s not like Centigrade or Fahrenheit. Those two scales are measuring the same thing and you can easily convert from one to another. You can’t convert between R128 and the crest factor results from the DR Database.

Source used by Roon for dynamic range

Roon uses EBU R128 to calculate dynamic range while most people in the audio world, including the Dynamic Range database, use a crest factor algorithm. Here is something I posted on the Roon forum: EBU R128 is perfect for volume leveling and the fact that Roon uses this to do volume leveling is great. People wanting the Dynamic Range Database DR numbers too is not a criticism of that choice. It is a realistic request based on the fact that the DR database numbers are more reflective of the actu…
