IMPROVE QUALITY OF ENTIRE AUDIO COLLECTION IN ONE CLICK
Simultaneously with normalization, MP3 Normalizer can apply Audio Effects, such as the Trimming of Silence, Fade-In, and Fade-Out for better playback.
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 more comprehensive 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.
EASY AS ONE, TWO ...
To normalize your MP3 files, you have to drop them in the application icon or window. The application will let you know when volume adjusting is done. MP3 Normalizer supports batch processing to process a single file or an entire tree of folders at one time.

TRUE BATCH PROCESSING
MP3 Normalizer allows to adjust a volume of the unlimited number of files and folders in one click and supports multiple normalizations simultaneously. If you process an entire tree of folders, MP3 Normalizer will replicate the structure of source folders. It is especially convenient if you need to adjust the volume of the whole music collection.

CUSTOMISABLE NORMALIZATION METHOD
By default, MP3 Normalizer analyses every audio track and applies the 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, which 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. As a result, it guarantees the best possible sound quality, saves your time and hard drive space.
*Note, we advise select Bitrate at 128 kbps, or lower meaning if you 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.
MP3 Normalizer transfers all tags from source .mp3 or .wav file to normalized file. If you would like to check or modify tags after normalization, please, use the Tag Editor.
