Further planting its roots on the VR SDK and development field, NVIDIA has just announced availability of two more SDK packages, for their VRWorks Audio and 360 Video suites. Now a part of NVIDIA's VRWorks suite of VR solutions, the VRWorks Audio SDK provides real-time ray tracing of audio in virtual environments, and is supported in Epic's Unreal Engine 4 (here's hoping this solution, or other solutions similar to it, address the problem of today's game audio.) The VRWorks 360 Video SDK, on the other hand, may be less interesting for graphics enthusiasts, in that it addresses the complex challenge of real-time video stitching.

Traditional VR audio ( and gaming audio, for that matter) provide an accurate 3D position of the audio source within a virtual environment. However, as it is handled today, sound is processed with little regard to anything else but the location of the source. With VRWorks Audio, NVIDIA brings to the table considerations for the dimensions and material properties of the physical environment, helping to create a truly immersive environment by modeling sound propagation phenomena such as reflection, refraction and diffraction. This is to be done in real time, at a GPU level. This work leverages NVIDIA's OptiX ray-tracing technology, which allows VRWorks Audio to trace the path of sound in real time, delivering physically accurate audio that reflects the size, shape and material properties of the virtual environment.
