In this talk, I will introduce the concept of perceptual indistinguishability in the context of VR and AR audio and talk about what is required to generate virtual sounds that are perceptually indistinguishable from reality. I will give a broad overview of the different stages of sound generation and interactions in virtual environments, discuss the challenges in achieving perceptual indistinguishability for VR & AR audio and present recent research developments towards achieving this vision.
Dr. Ravish Mehra is the Research Science Lead for the Audio Team at Facebook Reality Labs which is responsible for developing novel audio techniques to push the state-of-the-art for audio in VR and AR. He completed his PhD in Computer Science at the University of North Carolina at Chapel Hill in the field of acoustics and spatial audio. In his doctoral work, he worked on novel physically-based simulation techniques for simulating complex acoustic phenomena arising out of propagation of sound waves in large environments. His research interests span the fields of audio, acoustics, signal processing, and virtual and augmented reality. Dr. Mehra’s work in acoustics and spatial audio has generated considerable interest in the audio community, and his sound propagation and spatial sound system has been integrated into virtual reality systems (Oculus HMD), with demonstrated benefits.
