| Research Abstract |
A head-related transfer function(HRTF) represents characteristics of sound propagation from a sound source to each eardrum of a listener. The sound convolved with HRTF makes a listener localize a virtual sound. In this study, an auditory display system that is able to control up to 42 virtual sounds is developed by processing the convolution in parallel on GPU(graphics processing unit). This system can be implemented into a notebook computer. Therefore, the system also has a high portability.
