  3. Apply and download.

About this tool

Audio in videos frequently needs adjustment for the same few reasons: the camera microphone picked up the scene too quietly, the original had no automatic gain control, or you are assembling clips shot in different conditions and need them to match. Manual gain is the fastest fix when you know the source is simply too quiet or too loud. Normalisation is better when you have multiple clips and want them all to land at a consistent perceived loudness for a platform.

LUFS-based normalisation became important when streaming services and social platforms introduced loudness normalisation on playback. A video mastered at -10 LUFS gets turned down when embedded in a feed alongside content at -16 LUFS. Targeting -16 LUFS from the start means your video plays at the intended loudness without the platform compensating.

Questions

What is LUFS and why does it matter?
LUFS (Loudness Units relative to Full Scale) measures perceived loudness rather than peak amplitude. Social platforms measure uploaded content and adjust playback volume based on LUFS, which is why a video normalised to the platform's target sounds the same level as everything else in the feed rather than suddenly loud or quiet. -16 LUFS is the right target for short-form video platforms; -23 LUFS is the EBU broadcast standard used by European television.
Can I boost audio that was recorded very quietly?
Yes, but with a limit. Boosting a quiet signal makes the signal louder and also makes any background noise louder. If the original recording was in a quiet room, a significant boost is often clean. If there is consistent background noise, boosting it beyond about +12 dB will make the noise obtrusive. The audio noise reduction tool is better for those cases.
