Volume normalization

Um Sonos don’t have a time machine, so they have no idea what the volume for a given stream will be in the future. Normalization can only be done when all track volumes are known in advance (eg local library) or metadata is present from the service provider (which it isn’t). There is certainly no way to do it between disparate source (eg TV and Spotify). Same problem with ads on broadcast TV, for example.

christmas day and my playlist is al over the place volume-wise - come on sonos, when we going to see this actioned?  it doesnt matter what the level is set at - just need some consistency

Same. Wife asked me to rebuild xmas playlist with albums/songs that had consistent volume. Really big difference in some tracks. Notice it with the Apple music ‘Pure Pop’ playlist too. It’s very loud sometimes, and normal others.

I just joined what is supposed to be the premium listening experience of Sonos, and am very surprised that you have not worked out this basic issue with Spotify, after what I see is *years* of complaints about the issue (volume normalization). Hundreds of thousands of your customers are using Spotify with your speakers. Spotify's volume normalization works great with other speakers and wireless headphones. Sonos, stop washing your hands of your responsibility to work out this very obvious, annoying failure of the Spotify/Sonos integration, and pick up the phone and call Spotify today and work it out. I think you both can afford to do this. Thank you.

Thanks for the additional feedback, everyone. No further news to share at this time but we will be sure to reiterate the need for this functionality with the necessary department. Thank you. 

Be careful what you wish for! If you want the best audio quality then you probably don’t want to be using any automatic gain boosting or limiting. Probably fine for background music, but I would imagine it would be a poor compromise on hardware and software like Sonos which streams content from lots of different sources. Spotify know in advance what they are streaming as they benchmark every song as they encode it and send the volume data along with the music file. Sonos would no doubt have to use a very blunt instrument to achieve the same result with many different sources.

Lack of volume normalisation with Spotify is the biggest disappointment of otherwise good product. Please create an option to use volume normalisation as soon as possible. Changing volume from track to track is a real PITA.

Make sure it is optional. 

Not everyone wants to butcher their music with it. 

Why would this butcher music? If the only thing this does is play around with gain, from one track to the next? 

Depends what sort of music you listen to. 

I like a lot of classic and sound track albums, they often go from very quiet to very loud between tracks, it is how they are meant to be, volume normalisation tries to get them all at the same level. 

It is like having a TV where the TV automatically adjusts each scene for a 120nits white point, it will make every scene look like a mid summer day in the Bahamas, however, if the day is meant to be dull and overcast that is how I want to see it. 

The Sonos connect added in some Volume Normalisation a couple of years back, I noticed it because some albums I know well sounded well weird. You lost the dynamics between the ultra quiet tracks that went into the really loud ones. Peter someone on here worked out that if you set the volume to 88 (rather than fixed line out) it went back to normal, not ideal, but a work around. 

Volume normalisation is great when listening in my shop, at home at parties etc. But when I want to shut the door, turn down the lights and listen properly to albums with big dynamic changes to them I would want the ability to turn it off.
