+1, super excited to have Atmos. But no dts:X?

Just like Apple only used DD+ previously for iTunes stuff, they will only use Atmos now. But if they really do support 3rd party bitstream, then there is also a chance to get dts:x support.

My bet will be that they simply implement the DD+ Atmos variant used in streaming as Netflix does. Not holding my breath for true Atmos or DTS X or passthru. Apple has no own benefit by offering this. But a part of me really hopes that Apple will deliver what we would like.

I think there is only one way to do Atmos, and this is bitstream. Only the AV-Receiver can do the job, so they have to implement it. So hope they will open it for all apps.

So? It’s pointless to have the ability to bitream DD+ for us as basically all disc based content uses TrueHD for Atmos and not DD+.
And again, just because it can bitstream DD+ does not mean anything in regards to TrueHD or DTS-HD.

If I remember correctly, the limitation with current bitstream through Apple TV is that it only supports 16-bit audio, but for lossless tracks it needs 24-bit. If Apple sticks with DD+ and just adds Atmos metadata to the stream then they could probably just stick with 16-bit and that would prevent HD+Atmos from working. It wouldn't require a complete rewrite of their audio paths. Hopefully, though, they do implement 24-bit bitstream support.

The Apple TV support 24 bit audio. It already does when you’re playing ISO’s through Infuse. The only difference now it that the bitstream is decoded by Infuse to LPCM.

so is it related with hardware design or just a software problems?

Infuse has to decode it because it cannot output the full bitstream. Maybe it’s a different reason than bit depth, though. It could be hardware limited in the 4th gen, but only software on 4k. My guess, though, is that it is software limited on both, but maybe they would only do 4k because almost all of the Atmos content comes from 4k movies and blurays, not HD stuff.

I chatted with some Apple engineers at the tvOS and AVFoundation labs. None of them seemed to know anything. They could be being coy, but I’m starting to think it might not even require new APIs—bitstreaming will be a new consumer-facing option later this summer, and existing apps will “just work”. Fingers crossed! Regardless, I don’t think we’ll get any new info until closer to September.

Can you please explain this in other words to us? It sounds good the way you’re describing it.

Actually after thinking about it more, I’m not so sure. New APIs are almost certainly going to be required. But I have hope that they’ll exist.

Last I heard it was ATV4k API wont allow 192khz and this adds to why Passthrough audio doesn't work anymore. I doubt Apple cares at all for the small nitch that wants to play native local content. Their market is streaming content and IMHO design their product to encourage/control people towards the content they provide (iTunes) and business partners. I foresee the only Atmos they will allow will be DD+/Atmos for streaming content. Not what I personal hope, but my gut feeling is that is what we will get.

Sadly, I agree. Apple has never catered to the tiny highly technical segment of the market. Sadder still, we 4K ATV Infuse users represent an even tinier segment of that tiny segment: those who demand the best capabilities AND the best user experience. There's little hope of profits in such a low volume market.

Sweet! Now let’s hope they let 3rd party use it.

Do you have a 4th gen to try on? I don’t expect it, but would be nice to know.

Nice! How does it work? Is it bitstream audio? Or does the Apple TV 4K convert everything to lossy Atmos?

It must be detecting your Atmos receiver right? Mines just giving me Dolby Digital 5.1, Stereo or Convert Format off. Audio Output settings section is new too.
