Binaural sound generating apparatus, microphone array, binaural sound generation method and program

摘要

PROBLEM TO BE SOLVED: To provide a binaural sound generation device for generating a binaural sound from an observation signal, without requiring adjustment of array signal processing parameters.SOLUTION: n and k are integers satisfying a relation M=2n+k (n≥1, k=0 or 1), and the three-dimensional shape of a microphone array is a figure having symmetry when viewing from above. M recesses are provided in the lateral face of the three-dimensional shape, and 2n recesses of which are provided in pair, at intervals of 180 degrees when viewing from above. At least one microphone is installed in the recess, and an interpolation synthesis part generates binaural sound by performing interpolation synthesis of an observation signal.SELECTED DRAWING: Figure 5
