About this tool
Peak normalization scales the file so its loudest sample hits your target. Loudness normalization measures integrated loudness (LUFS, ITU-R BS.1770) and adjusts gain to match platforms like Spotify and YouTube.
All processing happens locally in your browser, ensuring complete privacy for your recordings and music.
