How Spotify's Loudness Normalization Actually Works

Spotify doesn't just play your track. It processes it, measures it, and decides how loud to play it for the listener.

Spotify's Loudness Pipeline

  1. Spotify transcodes your file to Ogg Vorbis / AAC
  2. Measures integrated LUFS (ITU-R BS.1770 standard)
  3. Normalizes to -14 LUFS (paid) or -19 LUFS (free)
  4. Turns down loud tracks, turns up quiet ones (with limiter)
  5. Applies its own limiter to prevent clipping

The Sweet Spot

Master to -10 LUFS with -1 dBTP. This is the optimal target — loud enough to sound competitive, dynamic enough to sound good.

True Peak

Always master with -1 dBTP true peak ceiling. Not -0.1 dBFS sample peak — actual true peak. Spotify's encoder can introduce inter-sample peaks.
