Abstract
A resonance signal generating method includes generating a first resonance signal of a specific pitch circulating through first loop processing by inputting an excitation signal to the first loop processing including first delay that delays the signal by a time corresponding to the specific pitch and first attenuation that attenuates the signal, generating a second resonance signal of the specific pitch circulating through second loop processing by the second loop processing including second delay that delays the signal by a time corresponding to the specific pitch and second attenuation that attenuates the signal, generating an attenuation change signal by adding the first resonance signal and the second resonance signal to each other, attenuating and inverting the added first and second resonance signals, and inputting the generated attenuation change signal to the first loop processing and the second loop processing respectively, and outputting the first resonance signal.
