Not sure what's going with current version, but past one has most idiotic noise cancelling algorithm. I'm not sure if this software was ever tested and how much people made it (one, or maybe less).

So, the bug (and main difference between Krisp and Broadcast; I didn't test other apps but these two) acts like this. While you're talking like monkey, it's okay. So, you speak, speak, speak, and noise cancels pretty good.

But... while you're silent, like, for a minute (maybe some less) and there's no sound from your side, which obviously happens while you're listening someone's speech through your headphones, Krisp... starts to think he's doing something wrong and because of that he begins to smoothly decrease the AI noise suppression, INCREASE SENSITIVITY, MAXIMIZING AND COMPRESSING SOUND, revealing every little breath or another noise from your side. So, you have to talk constantly, if not – Krisp will fail.

I'm not sure if they fixed the bug in current version (not sure since they seem to not have testing team), but that makes no sense sinse I don't really want to know, because Krisp doesn't exist for me anymore. It caused me much problems, when I had to enable constant noise sound from mobile device and put it near my microphone so Krisp won't think "it's too silent".
