I tried both volume adaptive + volume leveling after having analyzed all my audio files (9k in 2 hours).
But I'm not able to hear a difference with and without. And some audio tracks play louder than others...So I suspect it doesn't work at all for me.

Any explanation ? How to test or verify ?

Thanks

Few checks you can do.

Check the tags for R128 to see if they have values.
Add a few files to playing now, start playing them and check audio path; hover the mouse over DSP button and see the popup, it shows input, changes and output. Under changes it should tell you volume leveling is used and by how much.
Open DSP Studio and while still playing the songs and disable/enable the volume leveling/adaptive volume options. Unless the changes from volume leveing are 0dB, you should here a difference I would think.

Obviously, DSP studio doesn't work when you're bitstreaming. In this case audio path is empty I think.

When I ripped my CDs to the wav and flac using dBpoweramp, I checked the boxes to write track gain and write album gain on the DSP ReplayGain dialog box, but I did not check the box about R128. (I attached a screen cap that I hope shows up.)  Anywho, given that JRiver v19 is now using the R128 standard to analyze loudness and dynamic range of content, does that mean that I should re-rip my CDs with the “EBU R 128 Calculated Gain” box checked in dbpoweramp? And if, god forbid, the answer to that question is yes, then should the “LUFS Target Volume” setting be left at -23 or changed to some other value?

You just need to analyze the files with Media Center. Select any files that you want analyzed, right-click them and select Library Tools > Analyze Audio. Disable the "skip analyzed files" option if necessary. (I'm not sure if files created with dBpoweramp will require this option to be disabled)

Denti:
I have 80k+ songs. Will I need to re analyze all of these every time I add new music?

JimH:
No.
