How to normalize audio? What is normalization?

Audio normalization is a technique for increasing the volume of a recording by a certain amount until it meets the desired sound level. The result of normalization is an overall louder file or its selected area.

Imagine some tracks are too quiet, and you constantly regulate the volume instead of comfortably listening to music. Normalization makes loud and quiet songs sound the same.

Online audio normalization

On the Internet, there are plenty of free services that allow normalizing recordings without additional app installations. One of the most popular is Audio Tool Set.

  • Drag and drop an audio file to the timeline.
  • Go to Effects and choose Normalize.
  • Move the slider to set normalization values.

However, the online approach has some drawbacks. The editing session requires stable Internet connection, and you need to expose personal recordings to a web service.

Audio normalization on Spotify

When using Spotify, you can balance quiet and loud songs for a smooth listening experience.

  • Click the arrow in the top-right and select Settings.
  • Under Music Quality, enable Normalize volume.
  • Choose between Loud, Normal, and Quiet options. Each is suitable for different environments.

Once the necessary setting is applied, your music won’t disturb anyone in quiet places. Also, you’ll not be distracted by the noisy surroundings.

Does normalizing audio affect quality?

Normalization modifies audio parameters, including the dynamic range and Loudness Units relative to Full Scale (also known as LUFS). Therefore, professional sound engineers or audiophiles sometimes report insignificant changes in the output quality.

When correctly applied, normalization does not make sound quality poorer. It just makes recordings louder.

All music streamed on the radio is normalized — otherwise some songs would be quieter than others.


Audio normalization is a pretty popular effect used for mixing sounds and music production. This is one of the obligatory mastering steps for recording music albums, TV and radio streaming, where multiple tracks must sound equally loud. You can also normalize audio files online and on a computer for changing volume of a voice-over, for example.

Although some people believe normalization may result in a poorer audio quality, following our instructions lets you avoid such troubles.
