Room Impulse Response in Game Engines

Auralization in virtual environment was taken in consideration in a wider research on multisensorial reconstruction to extend current approaches stucked in visuals. In this study after the previous ones on evaluation of sound propagation and reverberation in Unreal Engine 4 (UE4), a possibility to import Impulse Responses into UE4 through the Wwise was assessed. Comparisons between the static geometric room acoustics software (Odeon) and UE4 with Wwise middleware were presented. The study was based on measurements of objective acoustic parameters. While the main drawback is emerging in case of dynamic auralizations, results showed that Wwise is capable to convolute the sounds into UE4 for static positions and fixed receiver and sound source orientations. Nevertheless, it has to be enhanced for the sounds which are dense with regard to early reflections.
