Description of Issue

I like the Roon UI, but it is really hard to find explaintion about the shown information.
For example under the shown music album the information is shown:
Album name
Album Artist
Format of music files
Bits of music files
kHz of music files

But then there is a symbol and behind a number.

Can you please explain me meaning of this number?

Thank you

I guess I found the explaination:

It is the Dynamic Range Level

Dynamic Range

So I guess, the higher the number the louder is the track?

Not sure, if I understood dynamic range…

From the link you found:

Dynamic range measures the difference in volume between the softest and loudest portions of a track or album

In your link, it’s explained that Roon’s loudness values are computed conforming to EBU R128 standard and the value is …

@Trompetfish

the higher the number

The more dynamic range the track has in terms of R128. This is not the same measurement used in the dynamic range database online.
