Being a great music lover, I have tons of MP3s saved on my iPod and laptop. Most of them are download from different sources online while others are copied from audio CDs and to other digital music devices. My main concern is that they don’t have the same music volume. Some songs are loud while others are almost inaudible. Whenever I play songs, I always need to grab a good hold of the volume controller just to make it suitable. Are there ways to normalize MP3 volume without messing up my files? Please help, thanks.

  • Open iTunes and click “Preferences”.
  • Click “Playback” menu tab.
  • Tick the checkbox that says “Sound Check”.
