How to normalize loudness — 3 steps
Upload your file: drag and drop or select an MP3, WAV, M4A or FLAC file (up to 100 MB).
Pick a loudness target: YouTube/Spotify (-14 LUFS), Podcast (-16 LUFS), TV broadcast (-23 LUFS) or Louder (-11 LUFS).
Download the result: hit Normalize and save the loudness-balanced MP3.
Loudness normalization matters when you have multiple clips or recordings from different sources or gain
levels — combined playback would otherwise sound jarringly uneven. Bringing everything to the same LUFS
target gives a smoother listening experience and avoids YouTube/Spotify automatically turning your audio
down for being louder than their platform standard.
Frequently asked questions
How is Loudness Normalize different from Volume Boost?
Volume Boost just multiplies gain. Loudness normalization measures perceived average loudness (LUFS) per the international standard, then adjusts precisely to a target level, keeping volume even and consistent across multiple files.
Which target should I pick?
YouTube/Spotify (-14 LUFS) for videos/music on social platforms, Podcast (-16 LUFS) for platforms like Apple Podcasts, TV broadcast (-23 LUFS) per EBU R128, or "Louder" (-11 LUFS) when you need it to stand out.
Why does YouTube automatically turn my video down?
YouTube/Spotify apply their own loudness normalization to balance volume across videos/songs. If your source is louder than the platform target, it gets turned down — normalizing beforehand gives you more control over the final sound.
Does it damage audio quality?
No. Loudnorm only adjusts gain and true peak, without heavy dynamic compression, so the recording's dynamic range is preserved.
Is my file safe?
It is uploaded temporarily for FFmpeg to process and is automatically deleted after 5 minutes. Nothing is stored permanently.
