Abstract:
A sound field effect adding apparatus comprising:an input terminal with which a musical tone of an audio band that includes a low frequency is input; a first generation means in which a sound field added musical tone signal is generated in order to produce a sound field effect that is based on a musical tone signal that has been input to said input terminal; a first output terminal for the output of said sound field added musical tone signal to a speaker system used for sound field reproduction; a second generation means in which a low frequency component of the sound field added musical tone signal that contributes to the production of the sound field effect that is related to the low frequency is generated which is different from the sound field added musical tone signal that is output by said first output terminal; a second output terminal with which the low frequency component that has been generated in said second generation means is output to an external device; and an electronic musical instrument that is provided with a speaker system with which audio reproduction of audio tones across the audio band including the low frequency is done, wherein an output signal that is output from said second output terminal is supplied to said electronic musical instrument and emitted by the speaker system with which said electronic musical instrument is equipped.
