GDC 2017: The Future of Audio in Unreal Engine

By Daniel Kayser

During GDC 2017 Epic Games' Aaron McLeran, Senior Audio Programmer delivered a technical presentation of the new multiplatform Unreal Audio Engine. Starting with a brief architectural description and walkthrough of the old audio engine and its varied technical challenges, he outlined the core design pillars of the new audio renderer. He then gave several demos of the audio renderer in action, describing how its used in Epic's VR game, Robo Recall, and what’s available now in Unreal Engine 4.15. He then gave a walkthrough of several exciting features which are coming to Unreal Engine 4.16, such as real-time synthesis, dynamic DSP effects, and physical audio propagation modelling via third-party collaboration. Finally, he demonstrates the steps to create a synthesizer from scratch and playing in a level in 30 seconds.
