PURPOSE:To generate a musical sound waveform signal rich in musicality by combining and multiplying plural musical sound waveform signals which are obtained by delaying an input musical sound waveform signal by every prescribed time and plural waveform signals which are obtained by delaying another input waveform signal by every prescribed time and adding the multiplication results and synthesizing the addition result with the input musical sound waveform signal. CONSTITUTION:The input musical sound waveform signal and another input waveform signal are delayed in first delay means 91a to 91e and second delay means 92a to 92e by every prescribed time, and plural musical sound waveform signals delayed in first delay means 91a to 91e and plural waveform signals delayed by second delay means 92a to 92e are multiplied in accordance with prescribed combinations and multiplication results are added by arithmetic means 93a to 93e, and a synthesizing means synthesizes the signal of the addition result and the input musical sound waveform signal in a prescribed ratio. Thus, what is called noise signal where a width is given to the frequency spectrum of the musical sound waveform signal is obtained, and this noise signal is synthesized with the input musical sound waveform signal to reproduce musical sounds rich in musicality. |
