Hi
Is it possible to perform audio analysis on a subset (ie. specific folder/s) of your music library (mainly to identify where it is constantly hanging).
TIA
No, unless you add a subset of folders as watched folders leaving others disabled.
‘Hanging’ could be as a result of unidentified albums, corrupt albums amongst a few other reasons.
On a tablet or a computer, check Roon settings, library page and skipped files. Might give you a clue if any particular tracks or albums are causing an issue.
Thanks for that. If I deselect the folders and then perform an audio analysis on the library, will the deselected folders then be removed from the library?
TIA
Just disable them, then they aren’t removed from Roon’s database. They will disappear temporarily from the library though until you enable the folder(s).
OK cheers, will try that over the weekend
