Love this feature, but I feel some of them are off. SRV Tin Pan alley is one of my favorite songs to listen to. I have the 176/24 version and when I Run it though the DR offline meter it gives me a rating of 13. Roon however has it at
5.
Roon uses R128 to measure Dynamic Range, not crest factor. For more information, see here: https://kb.roonlabs.com/Dynamic_Range
I’ve noticed this too. The DR values in Roon don’t match up to the analyzed DR numbers from JRiver. It’s a cool feature but not sure why the numbers are different?
So given the method that Roon uses for DR, what is a good DR number? For example, from the DR database http://dr.loudness-war.info/, anything above 14 is regarded as good.
