Customer Reviews of MP3 Normalizer

Nice lightweight simple program that does exactly what you need without any gimmicks or tricks.

I have been having problems with levelling withing reason my home produce backing tracks to be used with my Sony Minidisk and this App seems to fill the gap for me. At this very moment I would say it’s an excellent opportunity for Mac users to have their music at a reasonably controlled level.

I was trying to normalize files off Google drive, which gave a bunch of errors. I contacted support and Nick was there helping me out evenings and weekends. I changed my workflow, after purchase of music, I normalized the files locally and subsequently uploaded them to Google. Worked flawlessly, as designed! Thanks Nick.

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.

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

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
