Kinda related question: What system are you using? Is it FOSS by chance?

I’m not OP, just an expert on Spatial Audio.

Headphones are able to reproduce Spatial Audio mixes, if they’ve been binauralized, so the place and the system aren’t too relevant (if OP already set up their playback system).

Check out https://audiospace.soundingfuture.com/ It’s a new and experimental platform, but you’ll get a taste of Spatial Audio.

Spatial Audio is one of the terms used for anything with height information: Binaural and Ambisonics (although these two don’t always feature height), Dolby Atmos, Auro3D, MPEG-H or some experimental other formats.

Other terms that mean the same thing: 3D Audio, Immersive Audio, Surround+Height
