Abstract

　自由に移動可能なマイクロホンを用いつつもその現在位置の情報については処理に用いずに、音像定位を実現するマルチチャンネル信号を生成することが可能な収音装置を提供する。本発明に係る収音装置は、各チャンネルに対応して固定的に配置され、到来する話者の音声を収音し、対応するチャンネルの信号を表す基準信号を出力する複数の基準マイクロホンと、移動可能に配置され、到来する話者の音声を収音し実収録信号として出力する１つ以上の実収録マイクロホンと、各基準マイクロホンからの基準信号に基づいて実収録マイクロホンからの実収録信号に所定の演算処理を施すことによって、各チャンネルの信号を生成する信号生成手段とを備える。
