New gen consoles and modern GPU hardware have opened new opportunities for how sound propagation can be handled in games. In Avatar: Frontiers of Pandora, these new opportunities sent the sound crew on a journey to the realms of raytracing and voxelized path finding, towards the ultimate goal: a real-time propagation solution providing an obstruction and occlusion simulation that’s scalable, supports dynamic environments, uses existing data, requires no baking steps, no adding of rooms and portals, or tagging materials with absorption values. Spoiler alert: they did not quite get there! However, in this talk, two senior members of the audio team will present their intriguing and impressive final solution sharing what they learned along the way.
