MP3 Normalizer at Mac App Store analyse

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.

Smooth Audio Change

• ★★★★★   YogiFish 7 years ago ( v 1.0.8 )

Really like that I can balance the level of my sound files to play in a balanced way. No noticeable audio quality change. Worth it :)

Une arnaque je crois

• ★☆☆☆☆   Danny.53 9 years ago ( v 1.0.2 )

C’est simple… La normalization n’a que très peu d’effet. Je ne conseille pas.

Un bon petit programme pas cher!

• ★★★★★   Gujanito 8 years ago ( v 1.0.8 )

Destiné à normaliser les volumes sonores de nos MP3, ce programme s’acquitte de sa tache avec efficacité et discrétion. En plus, MP3 normalizer récupère les tags sur le WEb. Très bon achat pour cette app simple d’utilisation.

Great App. Some things still to improve

• ★★★★☆   Trompetosaurus 8 years ago ( v 1.0.8 )

First of all. Great App. Does what it should do. And the results sound just fine! Also the price is really really low! Two things I realized which may be worth improving: - The trim silence option could be a little more sensitive. Sometimes it cuts the attack a little which results in a little plopp at the beginning of the track. - Some files I tried to convert seemed to be broken. However the app didnt tell me but just produced a 0 second version of the track. Maybe there is a way to tell the user if something like this happens.

Increases the sound easily & without glitches!

Super easy to use and does the job perfectly. It increases the audio of my MP3 files noticeably and without any glitches. Love it! Thank you ;-)

Nope.

If you’re looking to boost your overall level output for MP3 files, this is not a good app for this process. Normalization is already an option in your system preferences.

Waste of money!

Their discription here and on their website specifically states. "It amplifies too quiet audio and decreases volume of too loud files or their parts automatically.” I tried this app on a single two person recorded interview MP3 file where the interviewer’s voice was too “quiet” and the person being interviewed spoke too “loud”. This app made no modification what so ever to the file I was trying to “normalize” the volume level on. I suggest you try the trial app at their website before spending any money here. Waste of money and time and I atleast want my money back. Thank You, dD...
