I thought with the among thieves collection they added tempest PS5 audio.
It does but not in the intended way.
There’s currently two ways to use tempest:
1. Object based 3D audio where the engine supports something like 5000 audio sources (far more than any game engine can support or process at once let alone the space that would take up in high fidelity - audio is very large)
2. Surround sound simulation in a binaural environment so imagine a virtual 5.1/7.1 system with speakers placed in a virtual space as you would expect from a surround set up, that is the version of tempest Uncharted collection supports.
It’s also worth noting that there is also stereo sound for headphones for most games, a binaural software solution for others (Battlefield) etc etc.
It’s a bit of a minefield and not covered very well in gaming media.
Also worth mentioning I don’t claim to know all of this as fact but I do remember reading about uncharted specifically and also how tempest can work.
Often the games with “lacklustre” audio on headphones are using the wrapper for tempest surround sound and technically support “3D audio”.
