Hi,
I have a USB microphone and I would like to improve how it sounds…and not only after launching an app like messenger or audacity.
I would like to have a better sound EVERYTIME I use it.
In audacity, ardour, resolve, you can improve how mic sounds like BUT ONLY once audio is recorded. SO I would like to improve it sounds ONFLY, like having filters (compressor, EQ, etc…) every time I use it.
I know how to do it under OBS Studio but for that, you must have OBS always running in background, which is not necessary the case when I do video calls on Facebook messenger.
Under MS Windows there is something call Voice meeter Banana that can virtual plug filters onfly so you can have EQ, compressor, noisegate every time you pick up your USB mic.
Something similar exists under linux and it’s pulsemeeter but I was not able to run it, as it returns me an error:
App sinks returned an error, audio backend probably crashed. Server will be closed.
Could not join subscribe_thread (maybe there is none)
closing client handler threads...
sending exit signal to listener thread, it should exit within 2 seconds...
closing socket
I uninstalled pulseaudio and pipewire and reinstalled them, but without any success. 
Is there someone who already has faced this issue or use another software to do the same thing I want ?
thx for helping me.
