A virtual reality (VR) audio rendering system and method of using HRTF functions to quickly capture new positional cues to pre-computed audio frames responsive to changes in user position relative to sound systems. In a client-server VR system, when a user position change is detected, the client determines an appropriate HRTF based on the new position and convolves them with a set of audio frames that have been generated by the server based on a prior position, resulting in modified frames for rendering. Meanwhile, the client propagates the new position to the server to generate subsequent audio frames for the corrected position. As HRTF convolution is computationally inexpensive, the latency between user position change and the resultant sound change as perceived by the user can be significantly reduced. As a result, an immersive VR experience of the user can be preserved.
