IOS 15 beta: Spatial Audio working with Apple podcasts

Just noticed that Apple spatial audio is now working with Apple podcasts app on Airpods Pro.
Don’t know if its a bug but it sounds awesome

I wonder how we’d implement that? I presume it’s simulated. Probably need to buy some (expensive) software from Dolby.

Just realised the iCloud link wasn’t working. Uploaded screengrab on imgur.
