What does Audio Normalizer do?

Audio Normalization adjusts the overall loudness of an audio track to meet standard broadcasting and streaming targets like Spotify (-14 LUFS) or Apple Podcasts (-16 LUFS).

Will normalization distort my audio?

No. The engine applies clean linear gain scaling combined with true-peak safety ceiling to ensure zero clipping distortion.

Is this normalizer free to use?
