Audio Normalization Standards for Social Platforms

Visual quality is only half the battle. If a user scrolls to your video and the audio is jarringly loud, or so quiet they have to reach for their volume buttons, they will scroll past. Understanding Audio Normalization (LUFS) is crucial for retention.

What is LUFS?

LUFS stands for Loudness Units relative to Full Scale. Unlike peak decibels (dB), which only measure the absolute loudest moment in an audio track, LUFS measures the perceived average loudness over the duration of the audio. It represents how humans actually hear sound.

Platform Standards

Most major platforms have adopted strict LUFS standards. If your audio is louder than their standard, they will automatically apply a harsh limiter to crush your audio down. If it's too quiet, some platforms will boost it (raising the noise floor), while others will just leave it quiet.

How to Mix for Social Media

To avoid having a platform's algorithm ruin your mix, you should master your audio to hit these targets before you render:

  1. Dialogue First: Ensure your dialogue tracks sit comfortably around -16 to -14 LUFS. Dialogue is king on mobile devices.
  2. Ducking: Automatically lower background music (sidechain compression or manual keyframing) when someone is speaking.
  3. True Peak Limiting: Set a True Peak limiter to -1.0 dB. This prevents distortion when the audio is converted from WAV to compressed AAC during the video render.
  4. Export Codec: Always use AAC audio at 256kbps or 320kbps for MP4 wrappers. It provides the best balance of quality and platform compatibility.

By adhering to the -14 LUFS standard, you ensure that your video's audio transitions seamlessly into the user's feed, preventing immediate swipe-aways due to volume shock.
