Sound Normalizer 6.21


Sound Normalizer has a nice and user-friendly interface. You can customize it with one of the four available themes and besides that multiple interface languages can be chosen for better user convenience. There is only one toolbar on top which has a total of nine icons which are named. When clicked, Batch processor opens a separate window where you can process multiple files at once. Otherwise the main window is capable of normalizing only one track at a time. The Convert icon will populate another window where you can convert the format of one or more audio files. You can even change some of the output file properties too.

Basic Operations

Sound Normalizer has a tag editor as well, which allows you to change the tag information of the converted or normalized tracks. The way the program works allows you to test the final result before saving it. There is a separate chart for each one of the audio channels and you can change the normalization level of each one of them independently if you want.


Sound Normalizer 6.21 is a wonderful application and besides its main function it is packed with some extra features and capabilities. The quality of the output files remains the same and we did not encounter any problems while we were testing the app. You should give it a try too, but keep in mind that its trial version will work for only 30 days.


  • Simple to use
  • File converter and tag editor at a glance
  • Multilingual support
