About Volume Booster
Volume Booster raises the loudness of quiet recordings, lectures, interviews or music by the number of decibels you choose. A built-in limiter catches peaks before they clip, so the result is louder without harsh distortion. Use it when a voice memo is barely audible or a song is much quieter than the rest of your playlist.
Frequently asked questions
Make audio louder online. Boost MP3, WAV and M4A volume by up to 20 dB with clipping protection and a limiter – free, fast and nothing is uploaded.
How much can I boost?
Up to +20 dB. For most recordings +3 to +9 dB gives a clear improvement.
Will boosting cause distortion?
Clipping protection and the limiter keep peaks under control.
Should I normalize instead?
Use Audio Normalizer to reach a target loudness automatically.
How many decibels should I add?
Start with 3–6 dB. About 6 dB doubles the signal level, and very large boosts also make background noise louder.
Can I boost the volume of a video?
Yes – Video Volume Booster raises the sound of a video while the picture stays unchanged.
