A technique that enables people to hear ultrasonic sources above 20kHz

For a hackathon last year, I patched Jitsi to play each person's audio from a different angle using the web audio spatialization APIs[1], and it really does help the cocktail party effect tremendously- people laughing or talking over each other (extremely common in physical conversations) don't make it impossible to understand the other person like when everything is mixed to a mono channel as it is with most video conferencing software.

That's an awesome idea & project, but mightn't it feel jarringly like being surrounded by people talking at you?

I think I'd at least want them all in the, say, central 160deg in front of me. At which point I wonder how good the 'spatialisation' is, how many people could be meaningfully supported.

Because you can't just have alternate speakers spaced out for maximal distinction - the same speaker suddenly coming from somewhere else would be even more jarring.

Really cool though.
