It seems Plexamp ignores replay gain metadata values. These work in other players, but not Plexamp it would seem. Is there a hidden switch to make Plexamp respect these? It makes it difficult to move over to Plexamp when other players like iTunes (Apple Music app) handles this well.
Sweet fades require much more detail to function correctly. They cannot work with just one loudness value for the whole file. Therefore Plex server is performing its own loudness analysis.
Settings - Server - Library - “Analyze audio tracks for loudness”
Make sure this is not disabled and the server is actually running during the time period for scheduled tasks.
I thought Sweet Fades was only for blending between tracks. What I am wanting is to have the per track Replay Gain settings to modify the playback volume correctly, as it does in Fubar 2000 and iTunes.
I thought maybe Loudness Leveling was used for Replay Gain, but it doesn’t seem to do anything if I am to be honest.
My “Analyze audio tracks for loudness” is set to “as a scheduled task and when media is added”.
So I am at a loss on why this seems to just plain ignore the Replay Gain values unless it is just strictly not supported at all.
Plex’s own analysis is used for both purposes.
Replay gain values which are embedded as meta data into the audio files were never used.
Is this a newly set up server/ library? Analysis may take some time.
I set this Library up months ago. The problem is that some of my recordings REALLY need to be boosted via Replay Gain, so I have modified their metadata using MusicBrainz Picard, which has worked super well with iTunes and Fubar2000, but sadly seems to do nothing at all with Plexamp.
Are you actually using Plexamp to play these tracks? Because loudness levelling is only supported on a few client types.
You can check for the presence of Plex’s loudness data by inspecting the Plex media info of the affected tracks. As long as you see a numerical value for “Loudness”, the analysis has indeed been performed.
Another caveat: if you are creating your own “albums” by combining tracks from different sources/releases, the whole loudness matching will fail. Because Plex does apply a general value for all tracks of one album.
I am on macOS Big Sur, and am directly using Plexamp 3.4.7. Also to be clear, I am looking for per song boosts though I do not create Albums from various tracks, I just use Albums directly as the recording media had dictated. While loudness leveling is useful, it would be even better to have the per song playback ReplayGain respected. All of my files are FLAC and always 44.1/16bit or higher.
I will also say that playing my music on Plex itself is a horrible and quiet experience, whereas Plexamp is closer to what I would expect the playback to sound like. Still not what I would get in iTunes or FuBar2000.
I would love a per song or per album volume adjust in the Plexamp application like how iTunes has built in. Really handy if I don’t want to go in and modify ReplayGain via MusicBrainz Picard.
Plex won’t boost individual songs to their max loudness. It will retain their relative loudness as it is in the original album context.
Plexamp can use the loudness analysis. The web app and several other plex clients cannot.
On top of that, Plexamp has a “volume boost” setting and the limiter which is needed is this case. Take a look into the preferences.
(Personally I wouldn’t want any player to attempt dynamics compression of my music [which is basically what “loudness boost”+limiter is]. But that is just a personal preference.)
