ABSTRACT:
An atmospheric quasi-sound generating system for music performance includes a reproducing device for reproducing the sound of a piece of music from a recording medium to obtain a musical sound signal, an effective sound library for storing effective sounds to generate any atmospheric sound for music performance, a selection device for select a desired effective sound from the effective sound library to output information on the selected effective sound, a position determining device for determining the acoustic image position of the selected effective sound on the basis of the information on the effective sound to generate acoustic image position information, a stereophonic sound generating unit for disposing the effective sound to the determined acoustic image position to thereby output a stereophonic sound signal containing these sound information, and a mixing device for mixing the stereophonic sound signal and the musical sound signal reproduced from the reproducing device. The mixing signal thus obtained is output from speakers.
