Electronic tone generating apparatus and signal-processing-characteristic adjusting method
As an electronic tone is generated in response to performing operation, the electronic tone is picked up by microphones corresponding to left and right channels, and picked-up sound signals thus generated by the microphones are then subjected to signal processing, such as reverberation impartment utilizing acoustic conditions of the interior of a room. Picked-up sound signals having undergone such signal processing are audibly reproduced via rear speakers. Then, once an automatic adjustment instruction is given from a user, measuring tones are reproduced stereophonically, and contents of the signal processing of the individual channels are adjusted on the basis of measured results of picked-up sound signals generated by the microphones picking up the reproduced measuring tones.
