Most JavaScript these days is basically compiled binary. Rarely is it very human readable.

Anyone have tips for using Jitsi? I've been thinking about moving off Zoom now that they're enforcing a 40 min limit even for one-on-one calls.

Does it create friction for folks who haven't used it before? Any suggested instructions to send with a meeting invite?

Wasm is about distribution of binaries, not about open source. Those are two different subjects.

When I install a program on my debian machine with apt-get, I also get binaries. But this doesn't mean that it is opaque right?

Is there video conferencing software that does spatial audio for conferences? What I have in mind is that it is often problematic to understand each other while multiple people are talking. It is much easier in person. I guess it all goes down to ability to focus on directial cues of an audio source. Currently everyone are placed inside one's head so they interfere much more this way.

Apparently FaceTime offers this. [1] Presumably Apple will allow other companies to do it as well, since they let them offer spatial audio in other contexts.

We've been using jitsi via zulip chat at work. It should be drop-in for at least small groups (one-on-one, handful of people - I have yet to investigate "conference" or "class room" size).

We do unfortunately see semi-regular lock-up/freezes where one end of the stream stops for ~30 seconds. Maybe this is worse in safari vs chrome/Firefox - we have not yet experimented much with different browsers. Or maybe there's a difference between x86_64 and arm/m1/m2.

Earlier quoted context omitted.

The original audio is significantly easier to understand. This may be technically interesting, but the noise suppression is aggressive to the point that it's eating critical signal with the noise.

This is the default for online conferencing. Everyone is way better off asking other party to repeat couple of words than listening for all that noise during the whole call.

But this might be better served with a simplistic voice activity detection, like in mumble.

I didnt understand the first three words, for Alice it was the next two, and for Bob it was the last four. How many people are going to ask to repeat?

Evolution taught us to understand over the sound of waves, crickets, rain, thunder, and more. It didn’t teach us to comprehend with half the signals masked.

As someone invited to a Jitsi meeting a while ago, not having any video background removal, a lot less audio processing and what looked like no video processing at all meant everyone was harder to understand, harder to see and any activity or clutter in the background was fully visible of course. I guess buying quality microphones and cameras for everyone involved would help. Detailed instructions are a good idea as well, I struggled a bit with the unfamiliar interface.

Personally, I'd stick with the big names, long remote meetings are strenuous enough even with all the quality of life features those offer.
