Full Tech Overview (13 min):

The first step in a good audio mix is normalization, meaning balancing the volumes of all the individual sound sources to get them within the same loudness level.

To create this plugin, a custom implementation of the LUFS measuring system was developed for Unreal Engine. LUFS is the new industry standard for measuring loudness based on the human ear perception and is the main driving force behind the normalization system.

기술적 세부사항


  • Batch normalization of procedural and linear audio assets (MetaSoundSources, SoundCues and SoundWaves).
  • Non-destructive normalization, only modifying the output volume level and not the sound data itself.
  •  Automatically filter out SoundWaves used within other selected MetaSoundSources or SoundCues, to preserve their internal balance.
  •  Basic and advanced settings for target loudless levels and accuracy level.
