MIXING DEVICE, METHOD, AND PROGRAM

摘要

There is provided a mixing device capable of easily increasing or decreasing a sound volume of a sound source specified by a listener while positions of a plurality of virtual sound sources are fixed. Azimuth angle difference detection means (24) detects an azimuth angle difference between a predetermined reference azimuth angle and an instructed azimuth angle decided when a listener specifies a virtual sound source space where virtual sound sources exist by using an operation unit (7). When the azimuth angle difference is 0 degree, mixing means (5) directly mixes the acoustic signals supplied from a plurality of acoustic signal channels and outputs the mixing result. When the azimuth angle difference is other than 0 degree, the mixing means (5) creates a state where positions of the virtual sound sources are fixed according to the reference azimuth angle and performs mixing in such a manner that the sound volume of at least one virtual sound source positioned in the direction of the instructed azimuth angle is greater than the sound volume of at least one virtual sound source when the azimuth angle difference is 0 degree.
