<P>PROBLEM TO BE SOLVED: To generate a waveform having a complex waveform shape in a simple and abundantly controlled manner. <P>SOLUTION: Phase information, which changes with the rate corresponding to frequency information, is generated in accordance with the parameter that specifies a stopping time and at least one sample point so that the phase information does not change for equivalent to the stopping time referenced by at least the one sample point. The frequency information, that is used for the rate with which the phase information is changed, is the frequency information, that sets the frequency of the waveform to be generated, being changed in accordance with the stopping time. By inputting the generated phase information into a waveform generating means which generates sample data of a prescribed fundamental waveform made of a plurality of sample points, a waveform that is made by deforming the fundamental waveform in accordance with the change in the phase information, is generated. By accomplishing the above, a waveform having a complex waveform shape is generated in a simple and abundantly controlled manner without changing the pitch by only specifying a stopping time and at least one sample point by the user. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
