Title:
共鳴信号生成装置、電子音楽装置、共鳴信号生成方法及びプログラム
Document Type and Number:
Japanese Patent JP6819309
Kind Code:
B2
Abstract:
A resonance signal generating method includes generating a first resonance signal of a first pitch circulating through first loop processing by inputting a first excitation signal to the first loop processing including first delay that delays the signal by a time corresponding to the first pitch and first attenuation that attenuates the signal, the first pitch being a pitch having a resonance frequency of a predetermined speaking length of a piano, generating a second resonance signal of a second pitch circulating through second loop processing by inputting a second excitation signal to the second loop processing including second delay that delays the signal by a time corresponding to the second pitch and second attenuation that attenuates the signal, the second pitch not being a pitch having a resonance frequency of any of speaking lengths of the piano or a pitch of a harmonic thereof but being higher than the first pitch, and outputting the first resonance signal circulating through the first loop processing and the second resonance signal circulating through the second loop processing.
