LoudFix

Normalise Audio for Spotify

Spotify normalises all audio to -14 LUFS before it reaches listeners. If your track is louder than -14 LUFS, the platform turns it down. LoudFix measures your audio using the ITU-R BS.1770-4 algorithm and applies a linear gain adjustment to hit the target exactly — no compression, no dynamic range loss.
