Something that lets me select a frequency above which all sounds would be filtered in real time? I don’t know if a software can separate the high pitched sounds from the rest of the sounds. If it was possible that would be perfect. If not just removing all sounds when any sound goes above the threshold.
Do you mean something like an equalizer? There’s a pulseaudio or pipewire plugin which can do exactly that. You should describe your use case more clearly though.
I’m sure ffmpeg (command line software) can, tho idk exactly how
You could try EasyEffects (FKA PulseEffects)
The Equalizer plugin should work, but there may be a better one.Couldn’t Audacity do it?
I’ve never used audacity in real time, isn’t it to edit audio files?
I’ve clarified in the question that I’m looking for something in real time.
Oh it’s for real time, Idk then sorry :/
