FWIW, at present, the Atmos and Dolby Audio on Apple Music are lossy DD+ sources upconverted to 24/48 PCM.$10/month for everything!! Lossless, Atmos, Dolby Audio, etc, etc.
Still a pretty good deal though.

DD+ actually streams at 48khz/16bit, I think when it's True HD it can go to 48/20 or 48/24.FWIW, at present, the Atmos and Dolby Audio on Apple Music are lossy DD+ sources upconverted to 24/48 PCM.

I bet if they ever go LOSSLESS we’ll all have to fork out more money for a ATV 8K or something similarFWIW, at present, the Atmos and Dolby Audio on Apple Music are lossy DD+ sources upconverted to 24/48 PCM.

Probably! Knowing most of us, we’d pay in a heartbeat ;-)I bet if they ever go LOSSLESS we’ll all have to fork out more money for a ATV 8K or something similar
Did I say otherwise?DD+ actually streams at 48khz/16bit, I think when it's True HD it can go to 48/20 or 48/24.
Yes you said "upconverted" which isn't entirely accurate.Did I say otherwise?
Yes Dolby True HD is based on MLP with some tweaking Dolby made to it.and isn't Dolby True HD on physical media essentially in an mlp container which can be 96/24?
Yes you said "upconverted" which isn't entirely accurate.
An inaccurate description. It is not "upconverted:" it is simply decoded by the Apple TV from lossy to lossless, without any information added or extrapolated. "Upconversion" implies the latter.Nothing to argue about here, the DD+ lossy source is upconverted by the AppleTV to lossless for delivery to the processor.
Upconverted implies it was upconverted from lossy to lossless. If you take something from .mp3 to lossless PCM, you’re upconverting it - even though no “info” is being added or extrapolated. Exactly the same with going from DD+ to PCM.. But if you want to split microscopic hairs and call it “convert”, have at it Webster.An inaccurate description.

Sorry, but you're just wrong as far as terminology is concerned. When you play back an MP3, it is decoded to uncompressed PCM before it hits the DAC. If it weren't, all you'd hear would be noise. Doing this at a file level—or what the Apple TV does for DD+ streams it passes to HDMI—is no different. "Upconversion" is the term used for when a lower resolution source is converted to a higher resolution output with additional processing intended to improve upon the source, such as upconverting standard resolution video to HD or 4K. In audio, upsampling is a form of upconversion. This is not that.Upconverted implies it was upconverted from lossy to lossless.

The end result is it goes from a lossy DD+ source to 24/48 PCM. Which is what I wrote - and you perfectly understood.
Thank you for this explanation, exactly spot on.Sorry, but you're just wrong as far as terminology is concerned. When you play back an MP3, it is decoded to uncompressed PCM before it hits the DAC.

Sorry but you and EricKalet are wrong. Image processing is not the same as audio processing and is not useful as an analogy.Sorry, but you're just wrong as far as terminology is concerned.

You can call the entire process of unpacking the DD+ and turning it into PCM “decoding” if you want. But it’s really a two-step process albeit a nuanced one.
Regardless, you are playing a pedantic game of semantics with no practical purpose.
That’s really cool how you again say I’m wrong, then say it’s really splitting hairs, then act like you’re taking the high road.If it's coded as 48/16 and decoded as 48/16 then there is no up or down conversion or additional processing. But really it's a game of potato vs. potato. Let's move on shall we?

It is streamed by the AppleTV at 24 bit, not 16 bit btw. I stand by my original post.
