SENZI and ASURA: New High-Precision Sound-Space Sensing Systems based on Symmetrically Arranged Numerous Microphones

Sensing of precise sound-space information is important to realize ultra-realistic communications. This study is aimed at realizing high-precision sensors of sound-space information for transmission to distant places. The proposed systems comprehensively sense 3D sound-space information, i.e., information for all directions for any listener orientation with correct binaural cues. In this report, we introduce two systems: "SENZI (Symmetrical object with ENchased ZIllion microphones)\´\´ and "ASURA (A Symmetrical and Universal Recording Array)\´\´. Results of computer simulations demonstrate that our proposed system can sense 3D sound space with high precision.
