Problem: Microphone has excessive white noise
Attempted solutions:
- I opened PulseAudio Volume Control, clicked the "Input Devices" and slid the bar to around 15%. This significantly improved the signal/noise ratio, but the problem now is that I have to also increase the volume to high levels in order to hear the recording, because the recording is silent otherwise. I don't want to damage my ears by listening to a different audio after forgetting to reduce the volume, so I need a different solution to increasing signal/noise ratio - a solution that doesn't excessively reduce overall audio volume.
- So I decided to go to this webpage (PulseAudio - ArchWiki) and have a look at "Microphone echo/noise cancellation" section. It turns out that "
<module-echo-cancel>
" is missing in the list of modules (I checked by first writingpacmd
in terminal, followed bylist-modules
). According to this ArchWiki page, it means that I need to create this module by writing in the terminal:
/etc/pulse/default.pa.d/noise-cancellation.pa
Now I'm perfectly able to enter/etc/pulse/
. But once I try to opendefault.pa
ordefault.pa.d
, I get this error message in the terminal:No such file or directory
. This error is hindering me from creating the module I need to increase signal/noise ratio for my microphone. How do I get past this obstacle? Thanks!
