| Outline of Final Research Achievements |
An omni-binaural recording system for 360-degree video was proposed. The proposed system consists of a spherical microphone baffle and a method of integrating recorded signals. This spherical microphone baffle has six hemispherical hollows. Each hollow is modeled on a cavity of concha. Acoustical characteristics of the proposed baffle were obtained by a numerical analysis, and spectral differences between two and six hollows were insignificant. Moreover, a generating of binaural signals for arbitrary listening direction was proposed. The proposed method was based on the weighted sum method and able to generate a desired binaural signals.
