ELECTRONIC PIANO APPARATUS, SOUND FIELD SYNTHESIZING METHOD OF ELECTRONIC PIANO AND SOUND FIELD SYNTHESIZING PROGRAM FOR ELECTRONIC PIANO

摘要

PPROBLEM TO BE SOLVED: To provide an electronic piano apparatus, a sound field synthesizing method of an electronic piano and a sound field synthesizing program for the electronic piano capable of reproducing stereoscopic sound images by stereoscopically localizing reproduced sound images and by enhancing presence, and synthesizing a virtual sound field in real time without limits of position and size of a generating sound source. PSOLUTION: A sound field synthesizing part 5 of the electronic piano is provided with; virtual sound source spot signal generating parts 31-1 to 31-13 which generate a plurality of virtual sound source spot signals for forming reproduction sound field by a grand piano for output channels of a speaker parts 6 respectively based on a plurality of sound signals form a sound source part; each virtual sound source spot signal of the plurality of the virtual sound source spot signals for each output channel outputted from a virtual sound source spot generating part; synthesizing part 43 for synthesizing other virtual sound source spot signals; and an acoustic effect part 44 for dispensing acoustic effects by a signal processing using impulse response with synthesizing virtual sound source spot signals for each output channel synthesized by the synthesizing part 43.
