What is loudness normalization?

It adjusts the average loudness of your audio to a target level measured in LUFS. It makes your audio sound consistent across different listeners and platforms.

LUFS stands for Loudness Units relative to Full Scale. It is the standard measurement for perceived audio loudness used by streaming platforms.

Will normalization distort my audio?

Loudness normalization adjusts gain across the track. It does not clip or distort unless the original recording was already at the limit.

Is normalization free?

Yes. Loudness normalization is a free feature in CalmClip.

Can I use normalization with silence removal?

Yes. Combine any editing tools in the same session. They all apply in one export.

Does it change the video quality?

No. Normalization only affects the audio track.
