About this YouTube audio loudness tool
YouTube auto-normalises uploaded video audio toward roughly -14 LUFS. If your mix is louder than that, the platform turns it down on playback — and you can't fight it back up after upload. Mastering AT the target keeps the audio sounding exactly the way you intended.
This tool applies broadcast-grade loudness normalization at -14 LUFS / -1 dBTP / LRA 11. It's particularly useful for YouTubers exporting from Premiere/DaVinci, podcasters cross-posting to YouTube and music creators running shadow uploads.

YouTube loudness FAQ
Doesn't YouTube target -13 LUFS?
It used to be reported as -13. The current value seems closer to -14 LUFS, matching Spotify and Apple. Either way, mastering to -14 LUFS / -1 dBTP gives you the safest landing.
Should I do this on the audio or the video?
Audio. Run the audio bed through this tool, then re-import into your editor and re-export the video. Or upload the audio file directly if your video is already finalised.
What about videos with very dynamic audio (e.g. action sequences)?
Loudness is integrated over the whole file, so a quiet stretch followed by a loud explosion still averages out. The big moments stay impactful.
Is my file kept private?
Yes. We don't analyse or index your audio.
