Interactive sound simulation: Rendering immersive soundscapes in games and virtual reality

The audio-visual immersion of game engines and virtual reality/mixed reality has a vast range of applications, from entertainment to productivity. Physical simulation is required in these applications to produce nuanced, believable renderings that respond fluidly to unpredictable user interaction. Simulating sound phenomena synchronized with visuals must be done within tight real-time constraints. The wave behavior of audible sound is quite different from visible light, requiring fundamentally distinct techniques. The resulting challenges have impeded practical adoption in the past, but these barriers are finally being overcome, with accelerating usage of advanced sound technologies in interactive applications today.

In this webinar led by Microsoft Principal Researcher Dr. Nikunj Raghuvanshi, learn the ins and outs of creating practical, high-quality sound simulations. You will get an overview of the three components of sound simulation: synthesis, propagation, and spatialization. For each, we will review the underlying physics, research techniques, practical considerations, and open research questions. Special focus will be on Project Triton: a sound propagation technology being designed at Microsoft Research that ships in major games and virtual reality experiences today.

Together, we will explore:

  • Challenges and requirements of practical interactive simulation
  • Fundamentals of the physics of sound generation, propagation, and perception
  • Overview of research in sound simulation and future research directions
  • Detailed discussion of Project Triton for fast sound wave propagation
  • Project Acoustics for plugin integration of Triton and HRTF spatialization in your projects
  • Various audio-visual demos of immersive sound simulation

Dr. Nikunj Raghuvanshi has over a decade of research and development experience at the intersection of audio, graphics, and computational physics. He has invented practical physics-based simulation techniques that are in wide use in the industry today. Dr. Raghuvanshi is currently a Principal Researcher in the Interactive Media Group (IMG) at Microsoft Research, an interdisciplinary team of researchers and engineers working on graphics, audio, and vision. Previously, his PhD work initiated sound simulation as a new research direction at The University of North Carolina at Chapel Hill and was acquired by Microsoft.
