I was talking with the live chat
and they said, it’s really important, that everyone with that issue reports it (via email) so they see how big the numbers are.
he also told me, it’s also a problem on Google Pixel. Issues with High Pitched/Children's voices and Google Pixel 7 Pro Microphone - Google Pixel Community
and that in Zoom there is an option to “use original audio” without noice cancelation.
we should try that too, to see if that helps.
but please everyone, report via email to the support!
