How to normalize a video's audio loudness

Ask Recut to export the video for the place you will post it. It measures the loudness of the whole track and applies one change of volume to reach that platform's level, about -14 LUFS for TikTok, Reels, Shorts and YouTube, with a limiter so the peaks don't clip.

Step by step

1. Attach the videoAdd the video whose sound is too quiet or too loud.
2. Ask for an export for the platformSay TikTok, Reels, Shorts, YouTube, the Instagram feed, LinkedIn or X. The export sets the loudness along with the frame.
3. Run itThe measurement and the change both run on your device, with no model cost.
4. Listen backCompare it with the original on the timeline. If you made the film in Recut from scenes, the assembly step can even out the loudness too.

What Recut does

Loudness here is measured in LUFS, the unit streaming apps use to set every video to a similar volume. If yours is quieter than their target, it plays quieter than the videos around it; if it is louder, the app turns it down and the peaks may already be squashed.

Recut measures the integrated loudness and true peak, then applies one gain to the whole track: about -14 LUFS for TikTok, Reels, Shorts, YouTube and the Instagram feed, and -16 LUFS for LinkedIn and X. The change is capped (never more than 30 dB up, or more than 6 dB past the point where the peaks need limiting), and a limiter keeps the peaks under the ceiling. When Recut assembles a film from scenes, it can bring the finished sound to -16 LUFS with peaks under -1.5 dBFS.

Tips

• Background noise gets louder along with the voice. Clean the voice first if the room was noisy.
• If music drowns out speech, turn the music down when you add it rather than relying on the export.

What it doesn't do

• This is one even change of volume, not compression or mastering: quiet and loud parts keep their difference.
• There is no loudness setting on its own outside the platform exports and the film assembly.
