That's not how i recall the presentation at WWDC. They did not mention having to use glasses at all. I may not be remembering this correctly but when i heard about this feature i was pretty psyched. I want to say it's limited to the Air Pod Pros and the article below says it is. But it also says the current Apple TV 4K will not support this feature. Guess it will only be through an iPhone or iPad. Hope that changes in future Apple TVs if this is true.
I found this summary at WhatHiFi:
During its typically slick, but untypically pre-recorded WWDC 2020 keynote briefing, Apple announced something that really piqued our interest: spatial audio.
Coming (along with a number of other new features) to the AirPods Pros this autumn, spatial audio is designed to deliver surround sound and 3D audio via your headphones. It’s basically Apple’s take on Dolby Atmos for Headphones and Sony’s upcoming PS5 3D Audio.
Apple’s spatial audio has a unique feature, though: it not only tracks your head movement using accelerometers and gyroscopes in the
AirPods Pro in order to position the sound accurately, it also tracks the position of the
iPhone or
iPad that you’re watching on, so that sound is also placed relative to the screen. This means that even if you turn your head or reposition your device, dialogue will still be anchored to the actor on the screen.
Apple spatial audio will be included in a firmware update coming to AirPods Pro this autumn. You’ll also need the new iOS 14 or iPadOS 14, which should be released around the same time. All of these updates will be provided free of charge.
It’s also worth noting that Dolby Atmos is only available on Apple devices launched since 2018. While you don’t need Atmos for spatial audio, the two working together will likely produce the best results.
On the software side of things, as long as an app supports 5.1, 7.1 and/or Atmos, it will work with spatial audio. That already includes apps such as Vudu, HBO Go, Hulu and
Amazon Prime Video. Stereo content can also be converted to spatial audio. All a developer needs to do is allow stereo spatialisation via an Apple plug-in.
Here’s something of a surprise: spatial audio is not coming to the
Apple TV 4K, or at least not in the first instance. That seems odd to us. True, AirPods are more often connected to a portable device than an Apple TV, but spatial audio seems a perfect way for those people without a surround sound system to get a taste of cinema-style sound while watching on their lounge TV.
Apple’s not explained why the Apple TV 4K isn’t getting spatial audio. The only reason we can think of is that it’s not powerful enough. The A10X chip in the Apple TV 4K dates back to 2017. Could it be that it doesn’t have the processing muscle for spatial audio? It’s possible, but that would also presumably preclude all pre-2018 iPhones and iPads from getting spatial audio. If this proves to be the case, it could be the best indication yet that a
new, more powerful Apple TV is on the way.
