    • A musical score extracting unit specifies areas of each of measures and the measure number of each measure on a musical score based on positions of musical-score composing elements such as part lines, staffs and bar lines. A music-data dividing unit divides music-data file based on time information in the music-data file to generate plural unit music-data files containing pitch information and time information for one measure. The music-data dividing unit specifies measures where repeat marks are placed based on sorts and positions of the repeat marks and positions of the part lines, staffs and bar lines on the musical score, thereby removing unit music-data file to repeat as instructed by the repeat marks from the plural music-data files to obtain a final unit music-data files associated with the respective measure numbers.
    • 音乐分数提取单元基于诸如部分线,员工和条形线的乐谱组合元素的位置来指定每个度量的区域和乐谱上的每个度量的度量数。 音乐数据分割单元基于音乐数据文件中的时间信息来划分音乐数据文件,以产生包含音调信息和一个度量的时间信息的多个单位音乐数据文件。 音乐数据分割单元基于乐谱的重复标记和部分线,人员和条形线的重复标记和位置的种类和位置来指定放置重复标记的度量,从而去除单位音乐数据文件以按照 来自多个音乐数据文件的重复标记,以获得与相应测量号码相关联的最终单位音乐数据文件。
