Sweet Fades not working in one of my music libraries

Server Version#: 1.23.2.4625
Player Version#: 3.4.7

Sweet fades is working fine in one of my music libraries. I added another seperate music library last week, and sweet fades isn’t working on this library, Can anyone point me in the right direction? Do I need to “analyze” the library to get it to work?

The one that does work, shows a like a volume graph as songs are playing, indicating it has data on it. Music in the new library doesn’t show this audio graph.

This occurs on my phone, and desktop. Using both web based plex and plexamp.

Sweet fades don’t work at all in the web app.

For Sweet Fades to function in general, you need to

  1. set the Scheduled Tasks to a time period where your server is actually running and where it has access to the media files Scheduled Tasks | Plex Support
    Make sure the time window is sufficiently large to get longer workloads done.
  2. go to Settings - Server - Library and make sure that “Analyze audio tracks for loudness” is not set to Never
  3. Wait until the server has analysed all of your library. If it is particularly large and your server is not blessed with a lot of computing power, it might take several days to process all albums.

Most recently added albums are processed first, so add an album and take a look into the Plex media info of a track, if it contains a “Loudness” value.
In Plexamp if the track has a loudness print under the album art, it has been analysed OK.

Hi @OttoKerner - thanks for all those tips. It’s been over 10 days since I put them to action. It’s still not working however. I extended the analyse time to 10 hours every day, but still nothing. I sorted the music by date added, to go to the first album and test it out, but it’s still not working (plexamp).

It does however work in a different plex library on the same server. Just this new one I’ve created it’s not working.

Any other tips?

Thank again.

Then you can only activate debug logging on the server and inspect them a few minutes after the maintenance time window has commenced.
Maybe you can find some clue whether there is a certain album which blocks the whole rest of the library from getting analysed?

I’d start checked albums in particular which are either ridiculously large, are downloaded from dubious sources, or were saved from damaged hard drives.
Also a common source of grief are files which are actually in a different format inside, but have been renamed to a different file name extension.

If you still have a lot of (old) mp3 files, use software like MP3Diags to find and correct flaws in them.
