I had the following problems with my microphone:
- Low sensibility
- Background noise
The white noise due to the high amplification needed because of the low sensibility in combination with background noise is disturbing in voice chat.
Fortunately there’s a PulseAudio module which improves the situation: The Echo Cancellation module.
Here’s how to enable it:
- Add the following line to /etc/pulse/default.pa (More information about the module can be found here)
load-module module-echo-cancel source_properties=device.description=input_with_filter
- Restart PulseAudio (command tells PulseAudio to quit. PulseAudio is only restart if it was started before with option –start.)
kill -sINT pulseaudio
- New input device with the name “input_with_filter” should be available
