Normalize Audio for Deezer
Deezer normalizes all audio to -15 LUFS before it reaches listeners. If your track is louder than -15 LUFS, the platform turns it down. If it's quieter, it may be turned up. LoudFix measures your audio using the same ITU-R BS.1770-4 algorithm and applies a linear gain adjustment to hit the target exactly — no compression, no dynamic range loss.
