My microphone has static background noise. I had a similar issue with Windows and there was a checkbox to get rid of background noise. After that my both microphones were working perfectly. But in Linux I couldn't find any solution. I tried to decrease volume to get rid of noise but it didn't help.

In Zorin Webcam microphone has much better sound quality than my real microphone(it is opposite in Windows), I think it is about drivers. so that I want to fix webcam microphone. Do you have any idea to decrease static noise? I need a checkbox as windows has

In terminal, use

Code:

locate module-echo-cancel

If you get a result, then we are in business.
Next we want to edit that file

Code:

sudo nano /etc/pulse/default.pa

Scroll to the bottom and add this to the file by copying/pasting:

Code:

### Enable Echo/Noise-Cancelation
load-module module-echo-cancel aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink
set-default-source echoCancel_source
set-default-sink echoCancel_sink

>> pulseaudio -k
>> pulseaudio --start

save and exit.

Alternative method:

Open your preferred file manager with Root privileges
Navigate to your root folder -under filesystem- and then to /etc/pulse/default.pa and open the file in your preferred text editor. Copy in the above snippet and then save and close.

I did it and restart pc. and noise has increased:

Also when I click the record button, Record app freezes for 3-4 seconds, after that start recording. One more thing: all record settings gone. I mean every button and option is passive. I can change anything.

As a result, I deleted that part and restart again. Everything normal right now. This experience makes me feel that my current static noise is not bad It is acceptable
