You might be interested in https://www.calla.chat/ ( https://github.com/capnmidnight/Calla ) which supports spatialized audio based on participant location on a top-down map.

Edit: in some ways, this might be totally off-base since it does involve a game and participant self-arrangement. Hopefully it's somewhat relevant, though!

I could be wrong, but based on the README this looks like it just sets speaker volume based on position - which is neat, but is not quite positional audio.

I wondered about that too, and found https://github.com/capnmidnight/Calla/commit/abc851b49bd1801... before commenting which seemed to indicate that there's at least stereo positioning. It's possible I'm mistaken though.

Oh interesting, it looks like you're right! They do appear to be using a StereoPannerNode rather than the full 3D PannerNode[0], but that is more than just speaker attenuation.

That's an old commit. It's had spatialized audio for the last month, at least.

I'm actually going to put a feature back in to let you select the audio "spatialization" model, because some folks have had trouble with PannerNode not working right. I used to have a selection between volume scaling, StereoPannerNode, and PannerNode. Been a little too busy at the day job to do it lately.

The now defunct Dolby Axon had this feature for up to 50 people. It was great, you could drag people in a grid around you (see picture in [1]). I’m still sad they discontinued it, it’s one of the few voice chat services that I would gladly pay money for.

I made a proof of concept chrome extension a bit ago: https://github.com/anateus/amphisonic

Currently re-writing it to be actually decent code. Basically, it takes up streams on the page and arranges speakers in a semi-circle in front of you, letting you adjust the radius (I've found for particular numbers of speakers there's an optimal radius for speaker separation).

I would love for MozIlla hubs (or any similar app for that matter) to allow one to set a webcam feed as your avatar's "head".

If anyone knows of such a thing please let me know. Would be perfect for socialising during quarantine and beyond.

It's at the other end of the spectrum, but Remotion is really cool and does what you describe. We wanted to get away from always on video, but I know lots of people like that. I cannot say enough good things about what the Remotion team are doing.

Kosmo.io has a poker app where your webcam feed sits at your seat at the table.

I have some multi-tenant PBXs based on Freeswitch however, I have not seen a positional audio feature in Freeswitch. Can you give more insight? Your link is the conference module and unrelated I believe.
