<P>PROBLEM TO BE SOLVED: To generate 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 in accordance with the parameter that specifies at least two sample points, is generated so that the information is repeated along a normal direction and a reversed direction between at least the two specified sample points. The frequency information that is used for the rate with which the phase information is changed, is changed in accordance with the parameter that specifies the frequency information that sets the frequency of the waveform to be generated by at least the two sample points. By inputting the generated phase information into a waveform generating means which generates the sample data of a prescribed fundamental waveform made of a plurality of sample points, the waveform, in which the fundamental waveform is deformed in accordance with the change in the phase information, is generated. Thus, only specifying at least two sample points by a user, a waveform having a complex waveform shape is generated in a simple and abundantly controlled manner without changing pitch. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
