FAQ
What is LUFS?
Loudness Units Full Scale, a standardized measurement of perceived loudness used by streaming platforms and broadcasters to keep audio levels consistent across different content.
Why -14 LUFS specifically?
-14 LUFS is the loudness target used by most major platforms like YouTube and Spotify, so matching it helps your audio avoid being automatically turned down or sounding quiet next to other content.
Does this actually process my audio file?
No — this calculates the gain adjustment needed based on your measured and target loudness; apply that adjustment in your audio or video editor.
