RESONANCE SIGNAL GENERATING METHOD, RESONANCE SIGNAL GENERATING DEVICE, ELECTRONIC MUSICAL DEVICE, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/135403
Kind Code:
A1
Abstract:
[Solution] The invention comprises: a first resonance signal generating unit (310) that includes a first loop unit including a first delay unit (311) which delays a signal by a time corresponding to a pitch x and a first attenuation unit (313) which attenuates the signal, and an addition unit (314) that inputs an excitation signal to the first loop unit; a second resonance signal generating unit (320) that includes a second loop unit including a second delay unit (321) which delays a signal by a time corresponding to said pitch x and a second attenuation unit (323) which attenuates the signal; a propagation unit (40) that adds, attenuates and inverts a first resonance signal circulating in the first loop unit and a second resonance signal circulating in the second loop unit, and inputs the same respectively to the first loop unit and the second loop unit; and an output unit that outputs the first resonance signal circulating in the first loop unit.
