Does ubuntu have a utility which can adjust levels for specific INPUT sound frequencies?
We are doing video conferencing and one of our co-workers has a lot of unavoidable ambient noise. He would like to isolate particular frequencies coming from his microphone and cut them before they are passed to the video conferencing software.
I checked out pulseaudio equalizer, but it seems to be limited to sound OUTPUT, not INPUT.
PulseAudio Equalizer and PulseAudio Volume Control are two different pieces of software. PulseAudio Volume Control will allow you to adjust input volumes so is probably what you are looking for. In a terminal type
sudo apt-get install pavucontrol
If that is not what you are looking for or is too basic, you could try JAMin, which is an Audio Mastering interface designed for input channels. It looks very in depth.
