Abstract:
1. A mixing system comprising: mixing means for mixing a plurality of audio signals and outputting a mixed audio signal to a sound reproducing apparatus which produces a plurality of virtual sound sources around a listener, the plurality of audio signals being supplied from a plurality of audio signal channels respectively associated with the plurality of virtual sound sources; an operation unit to be operated by the listener; and directional angle difference detection means provided in the operation unit, for detecting a directional angle difference between a predetermined reference directional angle and an indicated directional angle which the listener determines by indicating with the operation unit a certain direction within a virtual sound source space where the plurality of virtual sound sources exist, wherein the mixing means mixes the plurality of audio signals supplied from the plurality of audio signal channels without adjustment and outputs the mixed audio signal when the directional angle difference is zero degrees; and creates a state where the plurality of virtual sound sources are fixedly located with respect to the reference directional angle, and mixes the plurality of audio signals supplied from the plurality of audio signal channels by performing sound volume adjustment and phase adjustment for the audio signals so that the sound volumes of one or more of the virtual sound sources located in a direction determined by the indicated directional angle may be higher than those of the one or more virtual sound sources at the time that the directional angle difference is zero degrees, and outputs the mixed audio signal when the directional angle difference is other than zero degrees.
