Please Add Feature To Normalize Music Audio

My digital music library spans 2 decades with music collected from various sources and the output volume is all over the place when I play a music playlist of various artists. Please incorporate a feature in the Plex server that will normalize the output volume. I see others have mentioned this years ago but still hasn’t been incorporated in Plex.

Why don’t you try PlexAmp. It has all of the features you could want, normalisation, gapless playback etc.

Not available on Android or Roku. Seems to me it would be easier to implement in the Plex app across all platforms.

+1 to this. Former DJ with a music library normalized via MP3Gain, but Plex doesn’t read the normalization info so some of my songs come in super loud and then after I turn it down the next track is quiet.

If you do this, please also support normalisation according to EBU R128 (ITU-R BS.1770) which is more accurate to human perception than ReplayGain. And please let us define different target levels for different media (TV productions use -23 LUFS, (stereo) audio is usually somewhere between -16 and -13, mono audio: -19 till -16).

Another +1. My wife listens to our FLACs to sleep with, and Bryan Adams alone can very depending on the year released. Newers are louder than the older ones. So I have to set the volume on the receiver to the highest volume tracks, so “Cuts Like a Knife” is barely audible where “Depend on Me” is easy on the ears.
I ripped a lot of my music when my hearing was better, so yeah, I could compress and normalize and not tell the difference in quality, but that is a pain.

This is exactly why! Also when using plex for parties it sucks that some titles are very loud others are not, so I need to have the remote control at hand just in case.

Reg. ReplayGain: Plex server has all the information in case you got checked “Analyze audio tracks for loudness” server-side. Just the client-side lacks support except for plex amp. It is time to bring it to more clients although I guess the coding is probably very specific per client.

This is currently implemented in the iOS app.

… and it is in the latest Android release. Just stumbled about it out of pure luck. How did that elude me? Actually when did that happen. Cannot find any hint in any release note. Does it actually work well? Can the overlap be configured?

No, it configures itself for every song/song transition individually.
It uses data from the server, which analyzed the loudness progression of the song intros and outros at the same time when it analyzed the overall loudness of the song.

It was kinda snuck out, along with Tidal.

Thanks Otto, that explains why it wasn’t working properly on the train today with a bad Internet connection. I understand that an online connection to the server is needed, right? Now at home it’s just fine. I presume it also does not work in offline mode then?

No, synced music doesn’t have the necessary metadata on it - yet.

This doesn’t work if you’re Plex server for whatever reason can’t analyze the file. I opened another thread about this and all I got was a shrug for an answer.

Is this (or will it be) implemented for playing tracks on Sonos? This is where I primarily use my Plex music, and like others have experienced - the volume is all over the place!

Same here: I really would like to find a way to normalize my music while I’m playing it on Sonos!

Would also be cool to have it on special Android derivates like Samsung TVs (this is what they use as OS, dont they?).
