Customer Reviews of MP3 Normalizer - Page #2

Excellent app!

5 star rating

I've been using waterproof MP3 player while swimming and constantly suffered from volume issues. Some songs sounded so soft only dogs could hear them, while others almost ruptured my eardrum. I was initially sceptical about paying for an app that basically equalize volume, but at the same time could not find anything free that did it. I have to say that this app is well worth the money. I don't really know about technical stuff like LUFS and bit rates (and find the support pages somewhat difficult to understand), but all I know is that once I converted the songs they all normalized in volume! I like the option of deleting original "non-normalized" songs after converted ones are loaded: this eliminates the need of guessing which are which. There's also an option of automatically add converted songs to iTunes. Very nice app overall.

Very good app

4 star rating

Very nicely designed, feels "native" to MacOS, great that there are LUFS options

Great app!

5 star rating

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!!

Exactly What I Was Looking For!

5 star rating

I have copied over 550 songs from records, tapes, CD,s etc. into one file. Some song volumes are soft, low, loud. Many Genres from old classic to modern rock. Now, to the point. I am able to drag and drop one song or all into the MP3 Normalizer box and simply all are done very fast. Plus this app can clip slow beginnings such as from old LP Records. I created a folder called MP3-Normalizer as a destination place for them to wind up. Then copy and paste the whole bunch back where it started. I’m not very computer smart, but this app pretty much does it for me. Oh, it is a MP3 program so all songs going into it must be MP3. So convert any you want and bingo!

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.

Highly recommended

5 star rating

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.

A Godsend, with caveat

5 star rating

First, use Loudness, not Peak, normalization to adjust volume (in preferences, effects) for this app. Now the caveat: The default level to "adjust volume with Loudness normalization" is -15.0 LUFS. This setting is too high, causing high frequency distortion when played back on USB drives. Do NOT use any setting higher than -20.0 LUFS, that is, don’t use any number less than -20.0, and certainly not the default -15.0). With this caveat, I have nothing but praise for this app, a worthy counterpart to iVolume for iTunes m4a files. More versatile, in fact, because it does depend on the software of the playback program (e.g., iTunes) to equalize volume levels among tracks. $9.99 could not be better spent. For the first time in my life I can share music collections on USB thumb drives with family and friends, knowing that they won’t have to ride the volume control. Nice work, Brother Nikolay. You have made an invaluable contribution to the highest expression of humanity: music.

Very good, no point in hesitating, just buy it

5 star rating

I tried MP3 Louder first. That is also very good, however its a simpler piece of software for $2, suitable for a quick fix when you need it. But if you really want to squeeze the most out of your sound tracks, this is the one to get, for the extra options. I was particularly impressed that they’ve written a proper recursive tree walk, so that you can audio-normalise an entire folder hierarchy with a single operation. I wish everyone would do that, when they offer file based operations.

4 star rating

Era quello che cercavo da tempo, per normalizzare la mia vasta raccolta di mp3. Risultato finale di qualità e veloce. Assegno quattro stelle, solo perché, per chi come me ha i file residente in un disco di rete, durante il processo, qualche volta non riesce a creare il nuovo file, quello normalizzato e non è un problema di permessi. Mi sono arrangiato, copiando le cartelle in un disco usb e convertire queste, per poi ritrasferirle al disco di rete. Qualche passaggio “inutile" in più.

Igualar el volumen de todas tus canciones

5 star rating

Parece mentira que sea tan difícil encontrar una aplicacion que iguale el volumen de todas las canciones de la base de datos, de manera que cuando las escuchas no tengas que estar subiendo y bajandolo constantemente. En windows existia una que se llamaba MP3Gain, muy básica pero efectiva. Pues bien, MP3 Normalizer hace esta función perfectamente. Ahora puedo tener toda mi coleccion de musica en cualquier dispositivo, que siempre sonará al mismo volumen. Que alivio.
