Spotify Lossless coming to Sonos next month!

It is indeed good news, to bring it almost in line with Apple Lossless on Sonos (certainly to anyone’s ears it’ll be an equal). Although not sure I can congratulate Spotify on this ‘epic’ achievement after all these years...

I love their turn of phrase: “Lossless audio has been one of the most anticipated features on Spotify...”! 

I think they meant “Lossless audio is one of the most fundamental features of a music streaming service, and for us to take eight years to get there is quite frankly an embarrassment. That said, for some reason we remain the world’s most popular music streamer so offer no apology, and have been delighted to continue taking subscriber money for a lesser audio experience. We are now pleased to be where everyone else has been since forever - Amazon, Apple, Deezer, Qobuz, Tidal. And in another exciting development, the next highly anticipated feature - Atmos audio - is currently slated for 2035, but could well be later.”

Interesting. More technical details here:

• Tracks delivered at sample rates higher than 44.1 kHz (e.g., 48 kHz, 96 kHz) or bit depths higher than 24-bit are downsampled and/or reduced to a maximum of 44.1 kHz / 24-bit FLAC for playback on supported clients, with a fallback to 16-bit FLAC for backward compatibility.

That downsampling is good  wish I could get my non-Atmos Amazon streams to do that.

My reading of that part was it's for the Artists uploading their tracks in the best quality and Spotify take care of it from there

Spotify already downsample when you select a lower quality stream now?

From the video included in the original link, using Spotify Connect you can choose the audio quality.

Will wait to see what streaming options are available once lossless is available from Spotify within Sonos app.

Correct. Same as Apple.

Some mastering engineers prefer to control the SRC process by sending already converted files, however we ask that you deliver the highest native sample rate available. As technology advances and bandwidth, storage, battery life, and processor power increase, keeping the highest-resolution masters available in our systems allows for full advantage of future improvements to your or your client’s music.

I have a Sonos Amp and was wondering if I would have to wait for Sonos to update their app for me to stream lossless Spotify if listening via the Spotify Connect app?  

‘Sonos Connect app’ do you mean the Sonos Spotify Service in the Sonos App? Yes, I would expect there will be an App update, to give you the ‘eye candy’ lossless logo, similar to when App for updated for Apple Music Lossless in May ‘24, keep an eye on release notes.

My point is if Spotify releases lossless before Sonos makes the update to make it work from the Sonos app, will the lossless play via the Spotify Connect app which is how I normally play from anyway.  

I would expect their would be a requirement for a Sonos system update to enable lossless from Spotify Connect.
