Description Of Issue

Hi there, yesterday I migrated from a MacBook Pro to a i7 10th gen NUC. I followed every step from the tutorials carefully. When I finished the process, everything appeared to run smoothly, however I was looking at the settings, just to confirm that everything was as before, and I noticed on the Library tab that the analysis was running.
First) I don’t know why it is analyzing again.
Second) I have 43.951, and apparently Roon is analyzing not all but 34.856 of them. I looked at 10 random albums (at least), and they all had the Dynamic Range value and the waves showed up immediately on all the tracks I clicked.
Third) this analysis is running very slow, at about 2-3 track per minute.

Also, when I installed Rock, I did disable the previous storage, restarted Roon, edited the storage location (although the external hard drive and the folders locations were the same), and enabled it again.

Maybe I missed something?


So, I let it analyze for 4 hours, and when I looked again in the Library settings, it said “Analyzing: 34855 / 34856”. However, after waiting a good 20 minutes, that last track appeared to be stuck. I did a reboot and now it is analyzing again, “only” 33.968 to go, so just 888 tracks in over 4 hours?
Maybe someone with a similar issue could shed some light on this? From what I’ve been reading, I assumed the performance on a 10th gen NUC with dedicated ROCK would be better than a 7-year MacBook Pro? I don’t mind the new analysis (although I don’t understand why it is doing), but at this rate it will take a couple of weeks to finish.

Hi @Diogo_B

  1. If you followed all tutorial steps, you did a database backup, right?
    Restore the backup to circumvent reanalyzing your library.
  2. Edit your library settings to allocate more or less resources for analysis.

Hi, thanks for the reply. Yes, I backup regularly and I did one just before I migrated to the NUC, which is the one I used after ROCK was installed.
At a first glance, everything seems to be working properly, so I don’t understand why it is analyzing most of the files again. I didn’t make any system or database changes, or added new tracks after the migration.
I have 10 cores available on the Analysis speed, so I will experiment with that, but if I remember correctly, the MacBook did a full analysis of 40.000 plus tracks on Throttled, much faster than this.

Well, I guess support will have to jump in on that one, sorry!

Thank you either way. It’s not a dealbreaker, maybe just a bug or something. I increased the speed to 6 cores, it took one hour to analyze 1100 tracks, so going a little faster now.

Hi @Diogo_B,

Has analysis been completed since your previous message?
What does your Roon Settings → Storage tab look like, can you share a screenshot?
