MP3 Normalizer supports batch processing to process a single file or an entire tree of folders at one time.

The application will let you know when volume adjusting is done. To normalize your MP3 files, you have to drop them in the application icon or window. We recommend using To MP3 Converter for this purpose.

Please note that if you would like to normalize audio files of other formats, you have to convert them to MP3 first. You will have a new MP3 file with an adjusted volume level and applied audio effects as an output. However, you can apply it for a much more comprehensive range of purposes. There are just some common cases of using MP3 Normalizer.
