First Use

Ran 600 items through MP3 Normalizer (50 at a time), and all seems to be good. Will play in usb unit in car and will do a report after listening to that system. The program is easy to use and completes the process in short order.

Handy

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.

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.

Accurate!

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

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