I have currently made switch from windows to manjaro so I am really missing krisp which I was using in windows I have heard a lots of alternatives like noisetorch,rnnoise in linux but those are not working properly with my headphones(Boat rockerz 510) which has a inbuilt mic in it so when i use noisetorch in google meet it says this:
In my experience, more than good. And you can tune it as well. And there more than just noise suppression. All in all, just try it. It sits on top of your sound server, so just terminate it if you face problems. It hasn’t crashed even once in latest update with Pipewire. Can’t say the same for PulseAudio as I already left it.
There is a fix available for this now, but it requires building both PulseAudio and NoiseTorch from source. PulseAudio requires this patch to trickle down into distributions.
Unless you are willing to build PulseAudio from source, there is currently nothing you can do, but wait.
Just open your communication app (or respective web through browser), run the (Easy|Pulse)Effects, go to input tab (EasyEffects) or microphone icon (older PulseEffects), you will see source for the app with a toggle. Turn it on, enable whatever filters you want, and that’s it. For my needs, noise suppression and echo cancellation (I use separate devices for input and output) are enough, your mileage may vary.
