Yes spatial audio - you can definitely hear the difference.

Probably it’s headphones doing spatial sound wrong?

Spatial Audio also emulates having more than just stereo headphones. So, if the 5.1 soundtrack dictates that a sounds starts behind you and moves forward, SA will emulate that using software tricks.It's a well executed feature with a extremely limited scope/use case. I would not base headphone purchasing decisions on its availability.

Well, I tried with some one else who also didn't feel any spatial effect. I think it depends on whether the binaural recording was done with a head/ear shape similar to yours. So you'll just have to take my word for it that the audio positioning is very accurate. A good HRTF implementation should be calibrated to your head, Sony was talking about that when discussing the PS5's spatial audio: https:&#x

Seems like a fun use case for spatial audio on the airpods.

I hear stereo, but no 3d effect beyond distance from microphone attenuating volume.

Spatial audio is a really cool feature!

You can choose to enable spatial listening (as opposed to the stereo downmix), but you can't choose to use the original recording.

This is awesome. Have you considered trying to add spatial audio?

That part is old news, it's called Head Related Transfer Functions and even using a general HRTF works quite well. I presume you've tried Spatial Audio with airpods, or some similar system?https://en.wikipedia.org/wiki/Head-related_transfer_function.
