To provide an acoustic controller allowing a user to detect an approach object.SOLUTION: An acoustic controller 100 acquires sound signals from a plurality of microphones, respectively, and gives, to the sound signals, characteristics of physical changes when the sound signals pass through an object, on the basis of a distance from a reference position detected by a distance sensor to the object. The acoustic controller 100 generates sound information in an acoustic space on the basis of the sound signals having been provided with the characteristics of physical changes.SELECTED DRAWING: Figure 4
【課題】接近物体を利用者に検知させること。【解決手段】音響制御装置100は、複数のマイクから音信号をそれぞれ取得し、距離センサによって検出される基準位置から物体までの距離を基にして、音信号が物体を通過する場合の物理的な変化の特徴を、音信号に与える。音響制御装置100は、物理的な変化の特徴が与えられた音信号を基にして、音響空間の音情報を生成する。【選択図】図4
