audacity how to remove background noise

Good audio quality is important. But the best equipment or an entire recording studio is not always available. With poorer hardware or outdoor recordings, background noise can quickly occur. But even then, your recording can still be saved! With software like Audacity, such noise can be quickly removed by using audacity software.

Step 1

Start Audacity and open your audio file there. Then click and drag to select an area where only noise can be heard.

2nd step

Then you need to select " Effect " from the bar at the top. A menu opens with more options. Click on " Noise Reduction... ".

3rd step:

Now click on " Determine noise profile ". The window closes automatically. This allows you to choose which area of ​​your file to remove noise from. If you want to clean the whole file, just use the key combination [Ctrl] + [A].

4th step:

Then open " Noise Reduction " again via " Effect ". Now you can " Preview " the file. If the noise reduction is too strong or too weak, you will find adjustment options such as " Noise Reduction ", " Sensitivity " and " Frequency Smoothing " directly in the window. If you are satisfied, you only have to click on " OK ". Don't forget to save the file!
