mp3 tracks at different levels??

There is no sound levelling on Sonos. Which is one HUGE bugbear of mine. The streaming services themselves can do it when you’re in their app, but despite Sonos being able to adjust treble and bass of tracks coming out of its speakers, it seems unable to level out the volume. I seem to recall there is a reason, but it’s something I have wanted for years. It’s so annoying to keep having to turn the volume up and down all the time when you’ve got guests - it’s even worse when a playlist contains a mix of both Dolby Atmos and Lossless tracks (or a mix of music from Apple and Spotify) as the volume jumps up and down constantly….

In your use case, maybe there is software that can help but in terms of Sonos settings, you’re out of luck.

Years ago, their was MP3 Gain. Which pretty good. But was hoping for a "Sonos" type app?

Back in the day when streaming services were not a thing, when I used to rip, tag, file, analyse, adjust album art, etc I used dBpoweramp.

To ‘average’ the gain of a track, you have to analyse all the tracks, before they can be played. I assume a modern PC could do this a lot quicker than the tiny processors in the older Sonos devices.

So did I! It was great - and apparently I've just read that it’s still around? If you could batch run all the NAS drive tracks through it, that should solve the issue as it would encode them at consistent levels so they would be level on Sonos speakers…

Here’s what AI has told me: “If you're on Windows, it still runs fine. On a Mac, you can use it via Wine, or try a lighter alternative like MP3Gain Express – it’s more basic, but works well for batch adjustments. So if you used to rely on MP3Gain, there’s no reason not to bring it back!”

Don’t shoot the messenger if that isn't entirely accurate!
