Tip-1: Reducing Background Noise Before Recording

In this guide on “How to reduce background noise on mic on Windows 10”, the first tip that I would like to give you is to update the settings for the microphone on your Windows PC so as to minimize the chances of having background noise in your recorded Audio. That’s because, by default, these settings are not optimized on Windows for the reduction of the background noise. You have to make these changes before you start recording. All the steps that you should follow are explained below:

Step-1: Open Control Panel

First, go to the “Control Panel” of your Windows PC.

Step-2: Go To The “Hardware and Sound”

Once you are in the “Control Panel,” the next step will be to select the “Hardware and Sound” from the menu provided on the left side of the panel.

Step-3: Open The “Sound” Dialogue Box

Now, please click on the “Sound” option. As soon as you select the “Sound” option, a new dialogue box of Sound will appear in front of you.

Step-5: Select Your Microphone

Under the “Recording” tab, you find listed various microphones. Identify the name of the microphone for which you are trying to reduce the background noise and navigate to it. Select this microphone from the list. Remember not to select a wrong mic.

Step-6: Open The “Microphone Properties”

After you have selected your microphone, just click on the “Properties” button provided on the bottom right area. It will open up a new dialogue box labeled as “Microphone Properties.”

Step-8: Update Settings Under The “Levels” Tab

Step-9: Update Settings Under The “Enhancement” Tab

The next step, please navigate to the “Enhancements” tab of the same dialogue box in which you are. And, under this tab, it is recommended to check the checkboxes of the “Immediate Mode,” “Acoustic Echo Cancellation,” and the “Noise Suppression.” So you should check all of these three checkboxes.

Tip-2: Removing Background Noise or Cleaning Up Audio After Recording

My second tip in this guide on “How to reduce background noise on mic (Windows 10)” is to clean up Audio by removing the background noise after recording. You can perform this task with the use of software like Audacity. Audacity is free to use, and you will have to follow the steps mentioned below in order to remove the background noise from your audio with the use of this software:

Step-1: Download & Install Audacity

First, go to https://www.audacityteam.org/ and download Audacity software for free. Once downloaded, install it on your PC/computer.

Step-2: Go To “File” Menu

Now open Audacity to start editing the recorded Audio. Once you are inside the home screen of the application or software, navigate to the “File” menu and open it.

Step-3: Import The Audio Clip

From the “File” menu, go to the “Import” sub-menu and select the “Audio” option. As soon as you select this option, it will ask you to select the Audio you want to import for editing. Select the file and then open it.

Step-4: Select Empty Area

Once you have successfully imported or opened the Audio file in Audacity, you can start the process of reducing the background noise. For this, you should first select an empty area in the audio timeline. You will have to click & drag for selecting this area. And, by empty area, I mean the area in which there is only background noise. Hence, it is recommended to record audio without speaking for a few seconds at the beginning of recording so that an empty area (having only background noise) may be captured.

Step-5: Select the “Noise Reduction”

Once the desired empty area is selected, you should to go to the “Effect” menu available in the menu bar and select the “Noise Reduction” option form there.

On selecting the “Noise Reduction” option, a new dialogue box or window will pop up immediately. In this window, you will get to see the “Get Noise Profile” button. Click on this button. As soon as you hit this button, it will pick the background noise from the selected empty area.

Step-7: Select The Entire Audio Clip

Now it is the time to remove from the entire audio clip the similar sound or background noise that we have recently captured or picked from the empty area. You should press the “Ctrl+A” keys from your keyboard for selecting the entire audio clip.

Step-8: Again Open The “Noise Reduction”

Once the whole clip is selected, you should again go to the “Effect” menu to open the “Noise Reduction” window. Activate the “Reduce” mode for the Noise option provided in this window and just hit the “OK” button. Thus the background noise will be removed from the entire audio clip.

Step-9: Complete The Process

Once you have successfully removed the undesired background noise by following the steps mentioned above, the next step is to export the new filtered audio clip with a file format of your choice. For this, navigate to the “File” menu and select the “Export” option available in that menu. After selecting “Export,” choose the desired format like MP3, MAV, etc. and finally export it. And it is finally done!
