Audio Enhancement Built-In Feature for Eliminating Background Noise on Windows 11

I have to say that I’ve been waiting this kind of feature for quite some time. No matter it is built in on macOS, Windows or any free sound recorder app I’ve been testing. None was available at that time until I’ve found on Windows 11.

1. I use USB mic to record my voice with Microsoft app ‘Sound Recorder’. 'Sound Recorder' comes with Windows 11.


This feature makes ‘Sound Recorder’ not to record sound of fan, engine, finger snap, cough and I think it should be more than this that I haven’t found out.


Sometimes it records noise and then stop recording it (I can tell by looking at the wave shape in ‘Sound Recorder’) while that noise continues. I think it learn that that sound is unwanted sound so it decides not to record it.


What it records (based on my usage): human voice and bird sounds.


This feature can be turned on/off. If you want that noise you can turn it off in ‘Settings’.


To access this feature, connect USB mic then open ‘Settings’.



Search ‘sound settings’


 

Set output if you want.


 

At input, click your USB mic.


Allow apps and Windows to use this device for audio.



At ‘Audio enhancement’, if you want to turn it off, select ‘Off’.



If you want to turn it on, select ‘Device Default Effects’.


2. Open ‘Sound Recorder’ and start recording.


I have 2 laptops, audio wave shape in ‘Sound Recorder’ of the one that is cheaper is shorter than another laptop. When I playback that audio, sound level is lower. Other factors are the same – USB Mic, volume setting, gain setting of USB mic …



The noise I mentioned is not recorded but the cheaper laptop of mine gives me lower level of loudness.
