What the Audio Volume Changer does
Make a quiet recording louder or a loud one quieter by a set number of decibels, or normalize the loudness to the EBU R128 broadcast standard so several files play at a consistent level.
Options
- Change volume by −30 to +30 dB.
- Normalize loudness (EBU R128).
Good to know
Large boosts can cause clipping on recordings that are already loud; normalization avoids this.
