Highly recommended

I ditched Windows some time ago and what I missed was a wonderful old 2006 bit of Acoustica software, that converted MP3/WAV either as single or batch, trimming silence and normalising on the way. Well, what a delight to find 'MP3 Nomalizer' (offers to fetch 'Tag Editor Free' from App Store) and to find 'To WAV Converter' as well. Having both, MP3 Nomalizer and To WAV Converter, top that Windows software I used to use by a long way and provide more options, functionality and accuracy. . Normalise. . Trim silence from front and end. . Fade. . Right click 'Send To' in Finder. . File Hierachy. Both bits of software, a must have, on my system. Tag Editor Free is a simple quickie, but prefer Kid3.

Great app!

I have grown tired of having to constantly monitor the volume control. This morning I did some searching and came upon MP3 Normalizer. I first went to the web site to try it out before purchasing and after converting two files, I knew this was a worthwhile purchase! The cost of the app is a steal! I have converted 16 large MP3 files and each file took maybe 2 minutes or less to convert. So easy to use and I didn't have to read several pages of "how to's). I have listened to 3 files and "yes" the volume is normal and stable. The sound is not compromised. Wish I had gotten the app long ago!!

Ottimo

Otimo, funziona perfettamente. Sarebbe un’ottima miglioria il fatto di poter fare solo la normalizzazione, senza dover riconvertire il file. Infatti, se imposti nelle preferenze il formato corretto di MP3, è rapidissimo, altrimenti devi attendere il tempo della riconversione al formato che hai impostato. Per pochi file non è un problema, li gestisci singolarmente, altrimenti fai un’impostazione unica per tutti e aspetti ... ed i tempi, purtroppo, si allungano molto. Alessandro G.

INPUT FORMATS

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

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 our To MP3 Converter for this purpose.

EASY AS ONE, TWO ...

To normalize your MP3 files you have just to drop them in application icon or window. The application will let you know when volume adjusting is done. MP3 Normalizer supports batch processing so you can 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 entire music collection.

*Note, we advice select Bitrate at 128 or lower meaning if you will burn normalized MP3 files to CD and listen to it in your car. Many CD car players couldn’t read MP3 files with Bitrates higher than 128 kbps.
