> Audio calls also still suck. Commercials in the 90s advertised "crystal clear audio quality" - they stopped talking about it but it never materialised.

So this is a funny one because its definitely solvable but it's kind of a classic principal agent problem. There's a number of things that are going into 'clear audio quality'.

1. Receiver's audio output quality - This is rarely if ever the problem. People usually use their speakers/headset to listen to stuff besides corporate meetings, so they're motivated to have something at least good enough that they can enjoy their music, talk shows, whatever.

2. Bandwidth allocation - This... this really shouldn't be an issue, but it is because the user isn't paying for the bandwidth, whether that's classic cellphone calls, Teams voice, whatever. And so its in the company's best financial interest to compress the audio as much as is tolerable. This isn't really an issue if #3 isn't a problem and the user is in a place without too much background noise, but with open-plan offices, it is a problem if there's a lot of people talking.

3. User's mic quality - So in gaming communities, people will generally tell you if your mic sucks, because you're just some random stranger. And if your mic sucks and you want people to listen to you, you will probably buy a good mic eventually, tweak the settings etc. In a business context, my experience has been that the audio quality has to be pretty bad before anyone even says anything to the speaker. And then it's up to that person to either try to get it replaced by IT or pay out of pocket for a good quality mic. And this is assuming that they're technical enough to be able to pick out a good mic to begin with or even realize that its something they can solve.

I dabble in live audio. There's a huge amount that still could be done in the audio input space. Mic quality could be greatly increased for not much money, but most manufacturers stuff the cheapest component then can find into any headset <$150. Also, there's a lot which could be done with DSP (digital signal processing) before the mic even hits the computer.

You do see high quality mics and signal conditioning on the higher end systems, usually north of $250. And even then, it feels like that's a knock-on of paying for more headphone quality.

This is all overkill, solvable with the cheapest trash <10EUR pre-covid, setting up Mumble, and using push-to-talk. With moderation this even works for a few hundred people. Otherwise it's perfectly usable for about up to two dozen people, which should suffice for most meetings?
