Noise Reduction using Adobe Premiere Pro CC, VLC, and Audacity

Life is full of distractions, and in case of almost every distraction our mind diverts to the useless things. The same is the thing with the videos. Whenever, there is any kind of distraction in the video, the interest of the viewer may decrease. Therefore, one of the things that can be done to remove the distraction is the “noise reduction”. In order to reduce the noise, you may use an open source software, such as “VLC” and “Audacity”.

First open the VLC player, go to “Media”, and open “Convert/Save.” Click on “Add” and browse and add the video file for which you may want to reduce the noise. Click on “Convert/Save.” Select “Audio – MP3” under “Settings” with “Profile.” Click “Browse” and select the place, where you want to save the audio file. Click “Start” (shown in Figure 1). The processing starts, and the audio file develops.

Now you have the audio file of your video. Now open “Audacity” (software available as open source). Drag the audio file into the working area in the software. Select the audio by clicking on the left side as shown by red arrow in Figure 2.

Go to “Effect” and then go to “Noise Reduction…” It shows a window “Noise Reduction” with “Step 1” and “Step 2”. Click on “Get Noise Profile” in “Step 1” and select the area where there is no useful voice as shown in the Figure 3.

Now select the entire audio file again as shown in Figure 2, and go to “Effect” again, and select “Noise Reduction…” and click “OK.”  This process will remove the useless voice from all the audio file. Now go to “File”, go to “Export”, and click “Export as MP3” or any other option you like or want. Select the location, where you want to import, and click “Save.” Now you have the noise reduced audio file.Now import this file in Adobe Premiere Pro CC and place under the video clip to which it belongs. On the other hand, you can also search “noise” under “Effects” in Adobe Premiere Pro CC, and apply the noise reduction.
