Hey! I’m testing Plexamp and so far so good, but I realised that that fancy audio graph that shows in every screenshot doesn’t show up in 99% of my songs and only appears a regular trackbar. They don’t appear in any platform, so I guess it’s a server issue?

This loudness graph is created by Plex server.
Either when you add an album or during the nightly maintenance period, (or both).
Make sure that
- your Plex server is actually running during the time window set for the maintenance under Settings - Server - Scheduled Tasks
- Settings - Server - Library - ‘Analyze audio tracks for loudness’ is set to at least ‘as a scheduled task’
Songs played during a ‘Radio’ can also include songs from other people’s servers which are shared with you. So they must have these settings in place as well.
In the case of Tidal tracks (which may also occur during ‘Radios’), it depends a bit if this album has been played often enough by other Plex users before (and if the Plex cloud has gotten around to analyze it already).
If you inspect the Plex media info of tracks on your own server, you can tell by the presence or absence of the ‘Loudness’ value whether this analysis has been doen already or not.
Do also keep in mind that this analysis requires the file to be read in full from start to finish. Which might be the reason why some people with their media collection on cloud drives rather disable it.
side note for the technical minded: it is not a “waveform”, but really the result of an analysis with the EBU R128 algorithm to determine the development of “loudness” over the runtime of the track.
With it, you can discern pretty well if the mastering was done during the “loudness war” or before it.
