If you’re anything like me, your digital music library is full of songs from all sorts of different sources. And between all these ripped CDs, various online music stores and free downloads, there’s really nothing to ensure that they all come in at a steady volume level. The result: a simple song shuffle can quickly transform your quiet evening of music into an ear-blasting race for the volume dial.
But there’s an easy fix (assuming the volume difference isn’t too huge). Go to your iTunes Preferences menu and select the Playback tab. From there, check the box labelled Sound Check – it will automatically adjust the song volumes so they all come out at a relatively constant level.
