High-quality virtual audio scene rendering is a must for emerging virtual/augmented reality applications and for perceptual user interfaces. We describe algorithms for creation of virtual auditory spaces using measured and non-individualized HRTFs and head tracking. Details of algorithms for HRTF interpolation, room impulse response creation, and audio scene presentation are presented. Tests show that individuals externalize well, and find our interface natural. The system runs in real time with latency of less than 30 ms on an office PC without specialized DSP.
