  • Did you adjust (decrease) the audio input levels for your mic beforehand? If not, re-record the first minute of your recording in order to make a comparison. Also make sure that your mic doesn't pick up on electrostatic noise, generated by other electronics. Same goes for vibrations (computer fan). Generated noise in recordings can also be filtered out afterwards. Audacity offers an option for recording and also for different noise reduction/canceling filters (consult youtube tutorials). – v2r Nov 21 '20 at 11:23

I am currently using a headset with built-in microphone with Ubuntu LTS 20.04.1. Similar to you, I get lots of background noise in my microphone input. I get complaints when I speak on Zoom due to my workstation's fans being active. Unfortunately, I have not found a good way of eliminating the background noise automatically through Ubuntu. The best option is to record in a quiet setting. That may mean moving noisy items farther away. Also, if you can find a microphone that has noise elimination features built in, that would be a great choice too. It should be possible to eliminate noise in the microphone hardware so the input has less noise other than your voice.
