I’d love to have something like this over my board gaming table and not only play location ambiance through it but play clips in the spatial location of my players based on what they here.
Well, ignoring snazzy materials that take a pretty sophisticated factory like the original link, you could make something like this via a bunch of small full range drivers mounted in a ring and some of the dsp stuff available now. The computational requirements are low enough you could probably fit it onto a lot of maker style hobby controller boards too.
