Abstract (in Japanese) (See Japanese page) 
(in English) A novel signal processing for sound field recording and reproduction using parallel multiple linear microphone / loudspeaker arrays is proposed. In the conventional method based on the multiple-input multiple-output (MIMO) inversion of the matrix constructed from each transfer function between each microphone position and each loudspeaker position, the transfer filters are directly calculated from the inversion of them and might be quite unstable because the acoustic inverse problem is very ill-conditioned. In the proposed method, the transfer filters are calculated as each crosstalk canceller between each linear microphone array and each linear loudspeaker array in the spatio-temporal frequency domain. The results of the computer simulation show that the proposed method can calculate the well-conditioned stable transfer filters with low computational cost.
