PURPOSE:To obtain a good acoustic effect without necessitating a complicated operating technique, by assembling an operating function which controls the conversion frequency of the frequency conversion function of an acoustic signal, or the operating function which controls the size of a frequency converted signal. CONSTITUTION:A microphone is constitued by assembling the operating function which controls the conversion frequency of the frequency conversion function of the acoustic signal, or the operating function which controls the size of the frequency-converted signal. Also, an acoustic signal synthesizing device is constituted so that an operating device which controls the conversion frequency of the frequency conversion function of the acoustic signal, or the operating device which controls the size of the frequency-converted signal, can be load on the microphone. And an acoustic synthesizing system provided with a function which performs the frequency conver sion of the acoustic signal, the function which synthesizes the frequency-converted signal, with an original acoustic signal, and an acoustic signal delaying function, can be constituted. |
