I want a simpler feature: Auto-detect people not using headphones, and prevent them from speaking. Until they put some one. Ideally showing them some customisable scolding message. So far, any feedback / echo cancellation I've encountered just makes everybody's life miserable. Degradation to non-duplex voice (because all except the loudest speaker are attenuated down), "seaside noise" effect", etc. This is the reason…

And then there's another nag prompt if bluetooth headphones/mic are detected. The latency on those things can get horrendous, up to like 300 ms.

This would have 90% of the employees revolting within hours of instituting; for a very good reason.

I love meet because of how well it’s integrated with google cal

There's a Zoom plugin for GCal that makes Zoom's integration identical to Meet, including mobile app integration.

Good luck getting everyone in your company/org to successfully install an additional browser plugin

Do you think they are using some kind of inaudible-to-humans signal to coordinate this or is the unmodified audio good enough?

I could see this happening. Zoom for example already uses ultrasonic sound to detect what conference room a laptop is in for one-click screen sharing.

I wasn't aware audio hardware on laptops can emit ultrasound. Aren't those filtered to be below 22KHz?

I just want to say that this is really actually kind of mind-blowing from an audio engineering perspective. Outputting audio from multiple laptops in the same room is easy. Perfectly syncing it is harder. Implementing echo cancellation across all of that is quite a bit trickier than regular single-device echo cancellation. But then treating all the laptop microphones as a kind of microphone array, having to deal with…

From the praise, I assume you have first hand experience with it ? Which part did you use and did you see any rough edges ?

Meet, to me, is the perfect balance of functionality and simplicity (as an end user). And features like this only make that more apparent. Zoom and Teams always frustrate me, even though they're what I use far more often. It's too bad that video conferencing is largely a game of who has the most boxes checked - IT admins and A/V folk are the ones that need to be convinced, and Meet just doesn't ...meet... their needs

My Meet calls always end up pixelated, where Zoom looks perfect. That’s basically the only thing I care about after the audio quality, I often cannot read someone’s screen when shared via Meet. Zoom also feels lower latency but I never checked if that’s the case. Note sure if that’s because I’m not in the US.

You might be hitting QOS limitations where traffic from Google is bundled with YouTube et al and served at a lower priority ?

In my experience Zoom is always slightly better, but at a nitpicking level. I use meet day in day out, and fallback to whatever we have in hand if it's unworkable (pixelation would hit that line), and never saw zoom or Skype or discord being significantly better at these times.

Meet frustrates me immensely because I can't just fullscreen someone sharing an HD screen onto my HD screen and get 1:1 pixels with an overlay of faces (like Zoom does). Instead, I have to either not be able to read small text, or awkwardly pan in the recently-added "zoom" view.

I don't know how to do it with Teams either.

What if the resulting audio output of the digitally converted human vocalization has an inaudible frequency modulation or signature added to it which operates in a range inaudible to the human ear, you could then detect said signal and filtered out its source or merged / manipulated

Now fixing search, that would be truly mind blowing.
