Customer Reviews of MP3 Normalizer


4 star rating

It is a handy tool. Hower it loading mp3 file tags with loads of their self promotion adds. Other file formats than mp3 could be helful especially that making mp3 of mp3 is not a perfect recipe for audio quality

Hace muy bien su función.

4 star rating

He de decir que MP3 Normalizer hace muy bien la función de realzar el sonido de las grabaciones e igualar el volumen de los ficheros. Hace otras funciones, pero para mi estas son las principales. Solo una cosa, deberían pensar en algo para si un fichero ya ha sido pasado por la app y se pasa de nuevo, que no tenga que realizar todo el proceso de nuevo.

Need an m4a converter, some apple music are quite soft, otherwise a great tool for audio levelling and sonic properties maintain. Rast & reliable app

La mejor que he encontrado

En Windows utilizada mp3gain. Esta es tan buena como aquella. Respeta los arboles de carpetas y es rapida y eficiente.

Besser als MP3Gain

5 star rating

Läuft im Hintergrund und macht was es soll. Im Gegensatz zu MP3Gain for Mac hört man hinterher wirkich einen Unterschied.

Won't perform miracles, but helps normalize

4 star rating

Having tried several methods for normalizing audio files, this does a reasonable job. Unless you have time to manually adjust volume levels via Audacity or a similar app, this will suffice for most of your needs.

I recommend applications, very good for normalizing many files at once. Technical support will solve every problem. I would recommend !!!!

Great for podcasts

5 star rating

Great for podcast volume control. I found the parameters of "adjust volume with loudness normalization set to -13.0 LUFS" and "enable automatic volume control" to work well with all of my voice podcasts. Not sure what it would do to music. I tried some competing (cheaper or free) products, but this is the only one that worked well for my situation.

I needed this product after purchasing a recessed lighting/bluetooth speaker unit for my shower. Without this product, I could not hear some guests in various podcasts due to the shower noise. With this product, I have yet to miss any spoken words across many different podcasts.

Also, a couple of my podcasts have loud commericals (relative to the normal podcast) inserted automatically at random places that used to cause me to have to yank out my earphones at the gym to avoid ear damage. This problem has also been solved by using this product. Recommended!
