Normalize audio loudness

Upload an audio file that is too quiet or uneven and download it with broadcast-standard loudness (EBU R128). The format and quality stay under your control.

How does loudness normalization work?

The audio is analyzed and adjusted to a standard perceived loudness (−16 LUFS with a −1.5 dB true-peak ceiling), the same approach streaming platforms use. Quiet recordings get louder, and peaks are kept from clipping.

Will normalization distort my audio?

No — it changes gain smoothly rather than compressing aggressively. The result keeps the character of the recording, just at a consistent, predictable volume.
