PROBLEM TO BE SOLVED: To facilitate correction of a reproducing start point and a reproducing end point by correcting at least one side between the specified reproducing start point and end point and correcting a time interval from the start point to the end point. SOLUTION: When the start point showing the start point of a required section of the waveform data is specified like figure a, a beat grid making the start point the base point like figure b and having the time interval equivalent to a length of a quarter note is formed. Then, the end point showing the end point of the required section is specified like figure c. Then, when the end point is shifted, the end point is corrected to the nearest grid point like figure d. Further, a reproducing sound is outputted repeatedly and circularly based on the waveform data between the start point and the end point of the waveform data like figure e, and a metronomic sound is generated overlapping the reproducing sound. |
