PURPOSE:To obtain the more satisfactory presence by outputting not only a sound field by a musical performance sound but also an atmospheric sound except a musical performance sound in a concert hall. CONSTITUTION:In the sound field controller for generating an initial reflection sound signal and a reverberation sound signal by an acoustic signal and outputting them from the corresponding loudspeaker system 4, this controller is provided with an atmospheric sound source 1 for storing atmospheric sound signals corresponding to a direct sound, an initial reflection sound and an atmospheric signal except a reverberation in a concert hall, by a format corresponding to the direct sound, the initial reflection sound and the reverberation sound or a format corresponding to the loudspeaker system 4, and a mixing means 3 for mixing the direct sound signal, the initial reflection sound signal and the reverberation sound signal and the atmospheric sound signal. |
