MP3 Normalizer for Mac1.0.16

22 December 2020

Batch-normalize the volume of your MP3 files.

What is MP3 Normalizer for Mac

MP3 Normalizer improves the quality of MP3 files by amplifying quiet sections and decreasing the volume of loud files or passages automatically. It also smoothes sound peaks and minimizes clicks in MP3 tracks. Audio effects allow automatic silence trimming, as well as fade-in and fade-out for smoother playback of normalized files.

MP3 Normalizer can apply Peak or Loudness (EBU R128) normalization methods and amplify too quiet parts of audio with Automatic Volume Control. Target levels for both Peak and R128 methods; threshold for silence trim and duration of Fade-in and Fade-out audio effects are manageable.

To normalize your MP3 files, just drop them on the application icon or window. The application will let you know when volume adjustment is complete. MP3 Normalizer supports batch processing so you can process a single file or a whole tree of folders at one time.

I was looking for this a long time and finally found it a few years ago! What I like so much about this app is that it is able to bring very different styles of music together to one volume. And I absolutely love the trimming function with which you can erase then silence of tracks in the beginning or in the end. Makes it really sound like radio or Spotify. I still have the feeling (and that's absolutely my only tiny complaint) that songs without drums appear a little bit too loud after adjusting...

Works mostly like it is supposed to. Great sound quality!! The only glitch I've experienced was moving to a playlist in iTunes but not all the made it in there. I had to add manually.

According to my test, iDealshare VideoGo also helps to batch increase multiple mp3 volume at the same time: Step 1: Click Add File button to add the mp3 file, Step 2: Click "Setting..." button to open the "Advanced Settings" Window. Click the "Advanced" tab, then go to "Audio" column, click 100% tab on the right side of volume to select volume ratio from the drop-down list. Step 3: Click the "Profile" drop down button to select desired output format. Step 4: Click Convert button to start and finishe increase mp3 volume. It has both Mac and Windows version.

This is a hopeless idea – normalization of mp3s requires the audio to be compressed one more time (that is, you're making an mp3 from an mp3), which causes further quality loss.

As an audio professional, I can't recommend an app that alters files in compressed format (mp3, aac, etc.) as any conversion to a lossy format implies modifications and artifacts and is not advisable. It would not be so if there was a setting in the file's metadata like "play level" that you could change instantly, but AFAIK this doesn't exist. I've tested this app just enough to be sure it was actually "converting" the file and yes it does. Hence the reason why I'm not making a proper review, if anyone prefers normalizing their files at the cost of a (probably) imperceptible degradation for them, let it be. So the statement that it "improves the quality" of an mp3 is simply false — you could consider it "improves" the mp3 file itself by suiting your need for normalization or else, but not "the quality"... ;-) There's a lot to say about audio conversion, but one important (but neglected) thing is that any conversion can create so called "intersample peaks" thus creating distortion. Reducing the level should not be an issue, for that matter, but normalizing to 0dB is quite risky — I've seen intersample peaks of +3dB on very loud songs! In fact, I'm yet to find a converter that takes that into account and anticipates lowering the level BEFORE conversion of .wav files or CD. So in the end, I just wanted to warn people before they "normalize" anything: if you're an audiophile, you probably don't use mp3 anyway ;-), if you're an average user, you probably won't notice any damage to songs that were converted correctly on the first place; but reconverting an mp3 that has some click or other defect might increase them in a very noticeable way.

How does this compare to Levelator? I still use it regularly for my needs, but I would be curious to know if this fulfills the same need with support.
