Volume Booster
Make quiet audio or video louder, or even out the volume, without distortion.
Common questions
How does Volume Booster work?
Drop in an audio file or a video, choose Boost by a fixed amount or Normalise to a target loudness (like −14 LUFS for streaming), then run it. A look-ahead limiter always caps peaks just under 0 dBFS so the result never clips, even on a big boost.
Can I trust the output for production?
