I wonder why AI is used for these random things that nobody needs, instead of immediately useful things like calibrating microphone volume. I'm so tired of constantly redoing the echo tests, because the software is forgetting what microphone I used last time. Then there are also people who don't bother with the echo tests (I used to be that guy) and you can't understand what they are saying because of volume clipping.
