Audio and Sound

System for playing in-game sounds, including the use of SoundCue node-based audio assets.

Sound is immensely important to creating believable and immersive environments. From ambient sounds in the level, to interactive sounds from vehicles or weapons, to spoken dialog from the characters, the audio in the game can make or break the user's experience. Making the audio in the game actually sound like it should sound can be a difficult task. Unreal Engine 4's audio system provides tools and features to mold the sounds in the game to give them the desired feel. This is important because it means that a clean version of the sound can be produced once in an external application, imported, and then crafted within the engine to create the appropriate result.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
