| description | To provide a mixing device capable of adjusting the range of the sound field of an acoustic signal collected by three or more microphones.SOLUTION: A mixing device includes processing means that is provided corresponding to each of two sets of microphones determined on the basis of the arrangement position of a plurality of microphones and processes acoustic signals output from the two microphones of the corresponding set to output a first acoustic signal and a second acoustic signal, first combination means that combines and outputs first acoustic signals output from the processing means corresponding to the respective set, second combination means that combines and outputs second acoustic signals output by the processing means corresponding to the respective set, and the processing means process the acoustic signals output by the two microphones of the corresponding set on the basis of a scaling factor for determining the scaling factor of the sound field, a shift factor for determining the shift amount of the sound field, and an attenuation factor for determining the attenuation amount of the acoustic signal output from the microphone.SELECTED DRAWING: Figure 3
【課題】３つ以上のマイクで収音した音響信号の音場の範囲を調整することができるミキシング装置を提供する。【解決手段】ミキシング装置は、複数のマイクロフォンの配置位置に基づき決定される２つのマイクロフォンの組それぞれに対応して設けられ、対応する組の２つのマイクロフォンが出力する音響信号を処理して第１音響信号と第２音響信号を出力する処理手段と、各組に対応する処理手段が出力する第１音響信号を加算して出力する第１加算手段と、各組に対応する処理手段が出力する第２音響信号を加算して出力する第２加算手段と、を備えており、処理手段は、音場の拡縮率を決定する拡縮係数と、音場のシフト量を決定するシフト係数と、マイクロフォンが出力する音響信号の減衰量を決定する減衰係数と、に基づき対応する組の２つのマイクロフォンが出力する音響信号を処理する。【選択図】図３ |
