| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Weakness against user's position shifting is one of the most important problem of binaural reproduction using loudspeakers. In this paper, we propose a new method for inverse filtering of room acoustics with high robustness against user's position shifting by presenting a wavefront estimated from the binaural recording. To analyze and synthesize the wavefront, we introduce a new physical modeling based on superimposition of the wavefronts weighted by multiple sound sources. By following the fluctuation of the wavefront with time-varying filter, the analysis and the synthesis can be achieved regardless of the limitation of the number of the sound sources. Utilizing arbitrary component of generalized inverse matrix, the wavefront approximation does not degrade the accuracy of reproduction at the controlled area of the inverse filter. |
