Definitely a golden nugget find, glad I dug around, and dug deeper to find this. Naysayers please now find your way to the exit. "mic-drop"The best part of this is "Note: 5.1 and 7.1 audio files generated automatically and/or algorithmically from a stereo master are not allowed."
Same thing for Dolby Atmos.
So everyone that has been claiming that much of the Atmos material must be "generated" are barking up the wrong tree. Apple doesn't allow it.
Well, not so fast, there are always exceptions and downright lies. Just like HDTracks has been caught several times selling up-res'd files from CDs, it can happen here too.Definitely a golden nugget find, glad I dug around, and dug deeper to find this.

But it's still a golden nugget that I am happy to see unearthed right about now.

Good. Of course, that does not reveal how they detect and enforce such an edict.So everyone that has been claiming that much of the Atmos material must be "generated" are barking up the wrong tree. Apple doesn't allow it.
Ok, but this just tells us what the original source files submitted to Apple must be. It’s not at surprising they need to be submitted at industry standard resolutions.And here is the final word direct from Apple themselves:

The AppleTV doesn’t stream out DD+. It receives DD+ and upconverts it (decode & convert...whatever) to 24/48 PCM. Just check what your receiver is receiving. Your receiver is not handling DD+; it’s handling PCM.I can not find anywhere on Dolby's site or Apple site that Dolby Digital E-AC-3 (DD+) is streamed by ATV at 24 bit.
I did find this and highlighted what stands out to me as the final say on how DD+ is handled by audio equipment: "By means of an elegant conversion process, Dolby Digital Plus bitstreams, regardless of their source bit rate, are repackaged into a standard Dolby Digital format at 640 kbps. The conversion process does not decode the signal to PCM and reencode it, therefore avoiding the introduction of compounding coding artifacts." https://professional.dolby.com/glob...olby-digital-plus-audio-coding-tech-paper.pdf

I don't know about everyone else's setup or tech, but I'm seeing Atmos IN and 7.1 OUT no "upconversion or conversion to PCM"The AppleTV doesn’t stream out DD+.

Hmmm.My AVR shows ‘DD+ Atmos’ when I play Atmos movies and music from my AppleTV via HDMI. Same as when I play Netflix on my TV. Atmos streams as ‘DD+ Atmos’ via HDMI.
If these files are not being decoded from Atmos how can we hear Atmos? We’d be listening to PCM. The whole point IS streaming services deliver Atmos and we can LISTEN to Atmos.
I don't think I've ever seen that model selling new under $120, and that might have been during one of the periodic Apple sales at Costco. (On the other hand: Apple is unveiling new products this week. Don't think a new ATV is expected, though?) You can often find good deals on eBay, though.I'm not sure if this is the right thread or not, apologies if not.
Currently, I am listening to Dolby Atmos tracks from Apple music on my 2017 Macbook Pro connected via HDMI to my Dolby Atmos ready Marantz SR7013 receiver, even though my setup is 5.1 so the tracks are downmixed.
I'm considering purchasing the 2021 Apple TV 4K (64GB) to avoid having to plug in the macbook. I see amazon currently has it listed for $140. camelcamelcamel has the lowest price of $130 about a month ago.
Is this a good time to buy? Should I wait for Black Friday?
Thanks for the reply. Yeah, I realize that but I can still listen to the downmixed 5.1Even if you had an Atmos rig, you still wouldn't be able to get Atmos from your Macbook to your AVR over HDMI. For some reason--perhaps to force sales of the ATV?--Apple Music won't pass through an Atmos signal via HDMI, only the 7.1 DD+ core.
