LoudFix

Normalize Audio for Apple Music

Apple Music normalizes all audio to -16 LUFS before it reaches listeners. If your track is louder than -16 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.

Frequently Asked Questions

What LUFS does Apple Music use?
Apple Music targets -16 LUFS integrated loudness with a -1 dBTP true peak limit, following the ITU-R BS.1770-4 standard.
Will Apple Music change my audio's volume?
Yes. Apple Music normalizes all tracks to -16 LUFS. Tracks louder than this are turned down; quieter tracks may be turned up depending on the platform.
Does normalizing audio affect quality?
LoudFix applies a linear gain adjustment only — no compression, no limiting. Your dynamic range is fully preserved. The only quality impact is if you choose a lossy output format like MP3 or AAC.

Yes. LoudFix supports up to 15 files in a single batch. Drop them all at once, select the Apple Music preset, and download all results.
