| Abstract: | In this paper, we propose a coupled theory which uses headphones to reproduce 3D auditory scenes captured by spherical microphone arrays. This algorithm is based on the orthonormalities of spherical harmonics. The main advantage of our approach lies in its relative independence of the acoustical environment, along with its intuitive simplicity. Using a spherical microphone array, we first record the 3D auditory scenes, then the recordings are spatially filtered and reproduced through headphones in orthogonal beam-space of the head related transfer functions (HRTFs). Applications include telepresence, virtual environment, 3D music, video game, etc. We use the KEMAR HRTF measurements to verify our algorithm. In experiments, we use a hemispherical array for recording. The reproduction results are posted online. | ||
