MP3 Normalizer improves MP3 quality by leveling the sound and applying audio effects.
The trial version is available at amvidia.com/mp3-normalizer.
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 poorly-sounded records.
INPUT FORMATS
MP3 Normalizer accepts .mp3 and .wav files. You will have a new MP3 file with an adjusted volume level as an output.
CHOOSING A NORMALIZATION METHOD AND LEVEL
You can manage volume normalization and audio effects in the Preferences / Effects window. Set either Peak or Loudness (EBU R128) normalization method to enhance the volume of MP3 tracks. The enabled Automatic Volume Control feature makes voice records clear and hearable. Audio effects, such as Fade-In, Fade-Out, and Trimming of Silence, make the playback of music collections smooth and seamless.
PEAK NORMALIZATION
MP3 Normalizer applies the Peak Normalization algorithm with Target Level 0 dBFS by default. Such a 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 audio Peak Level. Loudness (EBU R128) Normalization is an excellent solution in such cases.
LOUDNESS (EBU R128) NORMALIZATION
EBU R128 algorithm analyzes the sound intelligently and similarly to how we hear it. Therefore, it is an ideal solution for unifying perceived loudness levels across a song list for a flawless listening experience. We recommend setting the Target Level value between -23 LUFS and -15 LUFS.
AUTOMATIC VOLUME CONTROL
Automatic Volume Control makes quiet parts of voice records clear and hearable. It amplifies silent segments of audio automatically. We recommend enabling Automatic Volume Control while processing interviews, podcasts, and audiobooks.
AUDIO EFFECTS
Applying Audio Effects improves the listening experience by making music playback continuous and smooth.
You can manage the duration of Fade-In, Face-Out, and Silent Threshold for the trimming. To apply these effects simultaneously with volume adjusting, enable them in Preferences / Effects.
Please find detailed instructions and related audio samples at amvidia.com/mp3-normalizer.
AUTOMATIC FORMAT SETTINGS
MP3 Normalizer estimates Bit Rate, Sample Rate, and Channels to apply optimal settings to output MP3s. As a result, it guarantees the best possible sound quality and saves your time and hard drive space.
If you want to convert to a particular Bit Rate, Channels, etc., change the Preferences / Format settings.
BATCH PROCESSING
MP3 Normalizer allows to adjust the volume of an unlimited number of files and folders in one click and supports multiple normalizations simultaneously. In addition, the application can replicate the structure of source folders when adjusting the volume of the entire music collection.
TAGGING ON THE FLY
MP3 Normalizer can transfer all tags from source .mp3 or .wav file to normalized file, create missing metadata from files and folder names, or load music tags from online databases - such as MusicBrainz, AcoustID, and CoverArt. If you want to check or modify tags after normalization, please use our Tag Editor.
RENAMER & FOLDER ORGANIZER
Rename and organize normalized MP3 files into folders according to Artist, Album, and other audio metadata set in Preferences / General / Destination Files.
INTEGRATION WITH ITUNES / APPLE MUSIC
MP3 Normalizer allows exporting tracks to a new or existing iTunes or Music app playlist quickly and easily.
