This is the best summary I could come up with:
It placed the call over a cellular network using the 3GPP Immersive Video and Audio Services (IVAS) codec, allowing callers to hear “sound spatially in real-time.”
The IVAS codec is part of 5G Advanced, an upcoming upgrade to 5G networks that could offer faster speeds, improved energy efficiency, more accurate cellular-based positioning, and more.
Currently, all phone calls made over a cellular network are monophonic, meaning audio is compressed into a single channel.
Spatial audio, on the other hand, makes it seem like sounds are coming from different directions as they’re delivered through multiple channels.
The IVAS codec could enable spatial audio in a “vast majority” of smartphones with at least two microphones, Nokia tells Reuters.
But, as pointed out by Reuters, we likely won’t see the more immersive audio and video calls on our cellular networks for a few more years.

I agree with you fully, but Spatial Audio is waaaay cooler than 3D TVs, and yes I did watch Avatar on a 3D TV on acid
But I really really have fun with audio. Also it’s not horridly expensive. While I’m working, I’m constantly looking around and hearing how different things are.

Nokia implemented stereo sound? Wow, welcome to 1881.
Meanwhile, the vast majority of people making calls are still going to have only one speaker, so it’ll still get downmixed to mono. Even if your phone has two, and you’re not holding it next to one ear, they’re still going to be so close together as to effectively be one point source.

At least in the United States, when you call somebody on the same carrier as you, you get that HD quality thing, and that improves the call quality a bunch versus the standard 8KB phone call. However, even still, when you call somebody on another carrier, you generally don’t get that high quality call. So it would be nice to get those high quality calls between carriers for everybody before moving on.

Voice over LTE and high definition calling is actually not the same thing. You can have a voice over LTE call and not have the high quality audio calling.

It’s not, I assure you. It uses psychoacoustic properties of audio to simulate actual surround sound. I’ve been using it in gaming for years. You can literally hear when an enemy is behind you vs in front of you, and anywhere in the 360° around you. You can easily pinpoint their location in your head.
Pixel Buds Pro have this same kind of programming and you can enable it when watching surround sound content on your phone. You can even have it play regular audio but make it sound like it’s coming from the direction of the phone. When you turn your head, the audio follows the phone and it sounds like the audio is coming from the phone in 3D, not just panned L or R in stereo. (I haven’t played with this much, and I hope I’m not misremembering that last part which iPhone also has.)
Here’s a computer generated example using these techniques. Headphones are required! Listen to this with ordinary headphones with no additional spatial processing enabled.
To my ears, it sounds like the 3 channels of the source audio are little spheres rotating around the top of my head like a halo. The music sounds distinctly different when it’s behind me or in front of me. The distance away from my head is not far, though.
A technique like this will never be perfect, and this is not the best example I’ve heard. The best would be using my Logitech gaming headset in a game. It’s not perfect because everyone’s ears are shaped differently, and your brain learns the microtonal differences which your specific ears cause as sound echo’s around your outer ear and ear canal. This might be why I hear these music examples as above my head while others might hear it revolve directly around their ears or perhaps a little lower than their ears.
I enjoy how ignorant people who don’t understand a technology dismiss is with snark and get upvoted by others. Wait, what’s the opposite of enjoy?

I make digital music myself. I’ve had that moment myself, where for a quick moment I thought, surely there could be some ‘proper’ way of rotating an audio source around your head.
And well, there is not, it is always just an effect thing.
As in, even in reality, our hearing is literally stereo, because we’ve got precisely two eardrums, two membranes that do the detection.
Yes, the ear flaps shape the sound, but you can do the same shaping with just effects. Make it a bit more muffled when it comes from behind, for example, and hope you don’t need to also portray that something muffled comes from the front. And of course, always slap a heavy virtualizer effect on there.
In the end, it’s smokes and mirrors that our brain then interprets as something spatial. I don’t have a problem with smokes and mirrors. I do still find it humorous, though.
I don’t really follow your logic, how else would you propose to shape the audio that is not “just an effect”.
Your analogy to real life does not take into account that the audio source itself is moving, so their is an extra variable outside of just stereo signal -which is what spatial audio is modelling
And your muffling example sounds a bit over simplified maybe? My understanding is that the spatial stuff is produced by phase shifting the LR signals slightly
Finally why not go further? “I don’t listen to speaker audio because it’s all just effects and mirages to sound like a real sound, what only 2^16 discrete positions the diaphragm can be in” :p
I got some AirBuds Proz and was blown the fuck away listening to music with Spatial Audio. I would love to try using them for games, but I’m sure they work like garbage on my Windows machines. Still, VERY cool tech.
They will just be normal earbuds on Windows, just like my Pixel Buds Pro. Even worse because I have to “forget” then rconnect the Buds from scratch every time I boot my PC. They will always say “connected” with no actual way to switch to them.
I listened to you link after commenting and it is absolutely an accurate representation of basic Spatial Audio for normal headphones! Thank you for sharing. I went through with Spatial Audio off and it astounded me, then was surprised when Spatial Audio ON made it less impressive. It’s because on Apple devices, it has the sound come more from where the video is coming from. For regular music, it doesn’t do that.
You’re not supposed to listen to pre-procrssed audio like that with additional spatial audio processing. You’re supposed to listen with ordinary headphones.
Phones, like landline phones or when you’re not using wifi calling, use a totally different method of communication than the internet. VoIP and WiFi calling do not use the phone part, they use the internet and are a completely different protocol/method.

Alrighty let’s learn some vocab
POTS lines, aka plain old telephone system, are what you’re referring to when you say landlines
When you’re calling off of Wi-Fi, most of the time you’re using a technology called VoLTE- Voice over LTE, which still functions on top of TCP/IP
The difference that matters here is the VoIP and VoLTE, as well as Wi-Fi calling are all digital protocols over TCP/IP networks.
If you really wanna get specific, most digital phone systems use protocols called Telephony, and SIP(session initiation protocol)
I work in telecommunications. This is pretty much exactly correct.
Not really a rebuttal to anything you said, but to expand on the fact that WiFi calling uses VoLTE “most of the time”, which is true because in some conditions SIP is used, but if you are using an Android or iOS phone, you are always using a modem, the voice line is never analog, and all digital voice communications are sent over TCP/IP.
