YouTube Loudness Checker (−14 LUFS)
Check your video's audio against YouTube's −14 LUFS normalization reference and a −1 dBTP true-peak ceiling.
YouTube normalizes to roughly −14 LUFS integrated. Mastering hotter than −14 gains you nothing — it just gets turned down — while leaving true peaks under −1 dBTP avoids codec clipping in the AAC/Opus transcode.
🔒 Everything runs in your browser via the Web Audio API — your audio is never uploaded.
