MP3 Normalizer improves MP3 quality by leveling the sound and applying audio effects.

MP3 NORMALIZER IS AN IDEAL OPTION FOR:

Equalizing the loudness across a song list;

Balancing the volume throughout a voice record;

Compression of audio for mobile and car listening;

Standardizing the loudness of tracks from different sources;

Improving the quality of old and poor-sounded records.

INPUT FORMATS

MP3 Normalizer accepts .mp3 and .wav files. As an output, you will have a new MP3 file with adjusted volume level.

CHOOSING A NORMALIZATION METHOD AND LEVEL

You can manage all aspects of normalization and applied audio effects in Preferences / Effects window. Set either Peak or Loudness (EBU R128) normalization method to enhance the volume of MP3 tracks. Enabled Automatic Volume Control feature makes voice records clear and hearable. Audio effects, such as Fade-In, Fade-Out, Trimming of Silence, make playback of music collections smooth and continuous.

PEAK NORMALIZATION

By default, MP3 Normalizer applies Peak Normalization algorithm with Target Level 0 dBFS. Such setting brings the loudest peak to the Target Level. Peak Normalization does not compress or distort the sound. However, the perceived loudness level is unpredictable as it does not correspond to the Peak Level of audio. Loudness (EBU R128) Normalization is an excellent solution in such cases.

LOUDNESS (EBU R128) NORMALIZATION

EBU R128 algorithm analyzes the sound intelligently and similarly how we hear it. Therefore, it is an ideal solution for unifying perceived loudness level across a song list for a flawless listening experience. We recommend set Target Level value between -23 LUFS and -15 LUFS.

AUTOMATIC VOLUME CONTROL

Automatic Volume Control makes too quiet parts of voice records clear and hearable. It amplifies silent segments of an audio automatically.
