How loud should your master be for Spotify?

Most platforms play every track at about the same volume. Spotify targets -14 LUFS by default: louder masters get turned down, quieter ones turned up only as far as the peaks allow. This checker shows your loudness and what each platform does with it. Nothing is uploaded.

Master Checker Pro

Compare your master with a reference track (loudness, dynamics and tonal balance per frequency range) and check multiple masters at once. One-time €4.99.

FAQ

How accurate is it?

Loudness is measured per ITU-R BS.1770, the same standard platforms use. Small differences of a few tenths are normal.

Do I have to master at exactly -14 LUFS?

No. Louder is fine; platforms just turn it down. Use "As on Spotify" to hear how it really sounds there.
