PURPOSE: A system for embodying real harmonic acoustic space is provided to simply embody an acoustic space for providing a spatial field sensitivity with various shapes by revising two channel signals corresponding to a characteristic of a speaker and the acoustic space, distributing a volume, and synthesizing the distributed volume as various shapes. CONSTITUTION: Sound field position adjusting units(50,60) receive left and right main signals and adjust a position of a sound field. Preprocessing tone space units(70,80) adjust a tone space. Sound field selecting switches(100,110) select the position of the sound field adjusted by sound field position adjusting units(50,60). comparing attenuators(30,40) perform a comparing attenuation in case of synthesizing left and right main signals with signals of sound field selecting switches(100,110). First synthesizing units(120,130) synthesize signals outputted from comparing attenuators(30,40) with signals of sound field selecting switches(100,110). Second synthesizing units(140,150) synthesize signals outputted from preprocessing tone space units(70,80) with signals of sound field selecting switches(100,110). Amplifiers(160,170) perform a differential amplification of reft and right signals. |
