About this Apple Music mastering tool
Apple Music's Sound Check feature normalises playback toward -16 LUFS — slightly more conservative than Spotify or YouTube. Mastering to that target keeps your track sitting at the same volume as the rest of the platform without an attenuation penalty.
This tool applies broadcast-grade loudness normalization at -16 LUFS / -1 dBTP / LRA 11. We don't analyse or index your master.

Apple Music mastering FAQ
Why is Apple Music's target lower than Spotify's?
Apple has historically been more conservative — Sound Check has lived in the iTunes / Music apps since around 2003 and was set to roughly -16 LUFS. Spotify and YouTube settled on -14 more recently.
Should I master once for both platforms?
If you're shipping to multiple services, the safest single master is around -14 LUFS — Apple will turn it down a bit and Spotify will leave it as-is. If you're shipping Apple-only, go to -16 for the cleanest fit.
Does this affect Apple's Mastered for iTunes (MFiT) certification?
MFiT is about file-level requirements (24-bit, no inter-sample peaks above -1 dBTP, etc.) more than a single LUFS target. This tool's -16 LUFS / -1 dBTP output meets the loudness side of those guidelines.
Is my file kept private?
Yes. We don't analyse or index your master.
