Step 2: Select Noise Profile

In this step, you need to select a part of the audio that contains only the background noise. This will be used as a reference to remove the background noise from the entire audio file.

This will analyze the selected portion of the audio that contains only the background noise and create a noise profile.

After creating the noise profile, select the entire audio file by clicking on “Select All” in the “Edit” menu. Then click on “Effect” and select “Noise Reduction” again. In the “Noise Reduction” window, adjust the “Noise Reduction” slider to the desired level of reduction. You can use the “Preview” button to listen to the audio file with the applied settings. Once you are satisfied with the result, click on “OK”.

Step 4: Export Audio

After removing the background noise from the audio file, you need to export the edited audio file. To do this, click on the “File” menu and select “Export”. Choose the desired audio format and location to save the edited audio file. Click “Save” to export the audio file.
