About Volume Booster & Normalizer
Quiet audio is one of the most common problems in content creation. Whether it's a podcast recorded at too low a level, a phone interview that's barely audible, or a voiceover that gets lost behind background music — volume issues can ruin otherwise great content. Our free Volume Booster & Normalizer fixes this in seconds.
Why use our free volume booster & normalizer?
Simply turning up the volume often introduces clipping and distortion. Our tool uses intelligent soft clipping and loudness normalization to boost your audio cleanly. With built-in LUFS metering and platform-specific presets, you can hit the exact loudness target for YouTube, Spotify, Apple Podcasts, or broadcast.
Pro tips
- 1Always normalize to LUFS rather than peak — it measures perceived loudness, which is what listeners actually hear.
- 2For podcasts, target -16 LUFS with a -1dB true peak ceiling for Apple Podcasts compliance.
- 3If you're boosting a very quiet recording, apply noise reduction first — boosting also amplifies background noise.
