Make a recording louder

The tool measures how loud the whole recording is and sets it to −16 LUFS, a common level for podcasts and speech: a quiet file gets louder, a very loud one a little quieter. Peaks are held down so the sound doesn't distort. The whole file gets the same change, so quiet and loud parts keep their balance.

Your file never leaves your device. It is converted right here, in your browser — nothing is uploaded.
