Ducking Audio System in Blueprint using Sound Classes - Unreal Engine 4 Game Audio
Today's video is about a more advanced technique used to duck audio. It is mainly used with dialogues or relevant sound effects. By ducking the background sounds, such as music or environmental recordings, we can emphasize specific sound elements.
To implement this system in UE4 we need to link the audio clips to different SOUND CLASSES. These will then be used as a sort of 'Music Bus', to route the signals into a SOUND CLASS MIX where we set each volume, EQ and so on.
