MP3 NORMALIZER IS AN IDEAL OPTION FOR:
- Improvement of the quality of speech records, like podcasts and interviews with Automatic Volume Control >>
- Improvement of the quality of older music records or poor quality records >>
- adjusting a sound of too quiet music >>
- the equalizing volume of audio collections >>
There are just some common cases of using MP3 Normalizer. However, you can apply it for a much wider range of purposes.
Please, note, that if you would like to normalize audio files of other formats, you have to convert them to MP3 first. We recommend using To MP3 Converter for this purpose.

CUSTOMISABLE NORMALIZATION METHOD
By default, MP3 Normalizer analyses every audio track and applies Peak Normalization algorithm with Target Level 0 dBFS. You can normalize either by Peak or Loudness (EBU R128) methods by choosing the required method in Preferences. To improve the quality of voice records - we recommend enabling Automatic Volume Control, a feature that applies special processing of voice records.

AUTOMATIC OUTPUT SETTINGS
MP3 Normalizer estimates Bit Rate, Sample Rate, and Channels, and applies optimal settings to output MP3s. It guarantees the best possible sound quality, saves your time and hard drive space.
Customization of MP3 Settings before normalization - Preferences / Format
*Note, we advise select Bitrate at 128 or lower meaning if you will burn normalized MP3 files to CD and listen to it in your car. Some CD car players couldn’t read MP3 files with Bitrates higher than 128 kbps.
MP3 Normalizer can apply fade-in and fade-out; trim silence in the start and end of audio tracks automatically. To use the effects simultaneously with volume adjusting, just enable them in Preferences.
