Best Volume Normalizers: How to Normalize Audio in Videos?

Aug 31, 2020• Proven solutions

Audio recordings are not always perfect since they can often be too loud or nearly inaudible. In case you are dealing with an audio or video file that has an unbalanced volume you can try to fix this issue by using the audio normalization features which video and audio editing apps for Mac and PC computers offer.

what is normalization?

There are two different types of audio normalization, peak normalization, and loudness normalization. The peak normalization changes the gain that is being applied in order to reduce the highest PCM sample value down to 0 dB, while the loudness normalization reduces the average amplitude to the chosen level. However, the majority of video and audio editing apps combine these two types of audio normalization into a single feature. So, in this article, we are going to show you how you can quickly normalize audio with different video and audio editing apps.

How to Normalize Audio?

The most common reason for using audio normalization features is to bring the audio level of several different audio clips to the same level. In addition, audio normalization can help you make inaudible narration or dialogue a bit louder, but you shouldn’t expect miracles, especially if the recording you’re working with is in low quality. We have selected top 5 best sound normalizer that you can use when video editing and the steps of how you can normalize audio in videos with these volume normalizers.

The app also lets you select more than just one track, so you can place audio files to two or more tracks and files from each track are going to be adjusted to the same audio level. Once you’ve selected a track or tracks that contain audio clips you’d like to normalize, head over to the Effects menu, choose the Normalize option and hit OK.

Audio Normalization Tips

A single scene can contain a lot of different sounds. The sound of someone’s footsteps, ambient sounds or the dialogue are just a few examples of sounds that are frequently used in videos and movies. The audio volume of each of these sounds shouldn’t be the same, because if the ambient sounds are as loud as the dialogue the audience may find it hard to understand what the characters in that scene are saying. That’s why you should use audio normalization only when you are absolutely sure that using the same audio volume level for two or more audio clips won’t disrupt the flow of your video.


Even though normalizing audio with each of the video editing software products we featured in this article is a straightforward process, this option should only be used if you have no other way to balance the audio volume of a video or an audio file.
