Increase a songs volume in iTunes
If you come across a song and it doesn’t play loud enough, you can increase the volume level of any song playing within iTunes by doing the following:
- Right click on the song name and select “Get Info”
- Click on the ‘Options’ tab
- Slide the Volume Adjustment slider all the way to 100%
- Click OK
The song will now play at twice the level it did before. In my experience this does not degrade the quality of the audio, so it’s a pretty safe choice. Boosting the song volume like this on a per song basis is a good way to fix the way a single song plays, but you can also set iTunes to automatically adjust song volume levels and iTunes will attempt to play all music files at the same volume level.
This works in the Mac OS and Windows versions of iTunes.
