SOUND SIGNAL GENERATING METHOD, SOUND SIGNAL GENERATING DEVICE, AND COMPUTER PROGRAM

摘要

A sound signal generating method, a sound signal generating device, and a computer program where high quality sound in which sound quality deterioration such as a noise sensitivity or a surface roughness sensitivity is suppressed is generated by processing the original sound signal to generate the processed sound signal are provided. The processed sound signal is generated by separating the original sound signal in the pitch unit of a waveform to generate a plurality of unit waveform signals, generating a repetition waveform signal for repeating the waveform of the generated unit waveform signals by the number of predetermined times for each of the unit waveform signals, and moving each of the repetition waveform signals in the order in which the original sound signal is formed in the pitch unit and superposing on one another.
