Amazon Music HD Available on Sonos

I just checked it out and it's absolutely not there, I thought it was but I must have been mis-remembering the FLAC listing in the Deezer app. That's what I get for posting so early in the morning... I'll make sure to bring it up with the team to see if it's supposed to be there, or something that can be added in the future.

Sorry folks for the inaccuracy.

Another thing - I talked to Amazon Customer Service today. They told me that tracks the are natively Ultra HD 24/96 FLAC are played in SD AAC in Sonos, not HD 16/44.1 FLAC.

So, we need some clarity and verification on this.

If one could see the streaming format in Sonos, this could be verified immediately.

For example, in Denon/Marantz Heos, I can find all of the format info and have already verified that I'm getting 24/96 and 16/44.1 FLAC (depending on the source track) from Amazon Music HD.

The problem with Heos is that Amazon Music's "My Music" is absent, so you have to manually search for each track/album, and you don't have access to personal playlists (a big miss for Heos in terms of Amazon Music implementation).

I'll check in on that for you adam2434 to make sure I have the right answer. From what I've heard, it should be largely the same library, but I don't think there's a conversion to the HD that takes place if the track is only in 24/96.

The team is still working on some things as well, so you'll see the service on Sonos change a bit over time. Though I don't have specifics to share right now on those changes.

I can see some 'Ultra HD' content in the Amazon Music app on my phone which is in 24/44.1. The same content streams on Sonos at 16/44.1. (It's clocking around 1 to 1.1 Mbps.)

I can't speak for 96kHz though as my phone is not capable of handling it, and in any case I wouldn't know where to look for 24/96 music.

Basically Amazon has to be able to stream at whatever rates are mandated by the native client app's platform.

Ryan S, thanks for looking into this.

Ratty, 1 to 1.1 Mbps is a good sign, as 16/44.1 FLAC is usually around 850-1000 Kbps for stereo tracks, IME.

It all depends how complex the music is. Anywhere from 500 to 1200 kbps is quite feasible.

Unrelated and not relevant to Sonos, but I wonder where Amazon is getting the Ultra HD (24 bit) tracks.

Digital masters from the studio? New 24 bit digital masters from analog tape?

Just curious...

There's lots about. You only have to look on, for example, 7digital or Qobuz.

The ability to tell what file format and bitrate is currently playing from a music service would be a very welcome addition to the sonos controller app in my view. Please could this be added to an update. The same applies to radio streams.

I really meant, in general, where do these hi-res files come from?

I assume the record labels have them as master transfers from the original recordings, and provide them to the streaming services and download sites like HDtracks.
