            Enpath = "%s%s/%s"% (endir,file,enfile) #英文文件的路径            cnpath = "%s%s/%s"% (Cndir,file,enfile.replace ("En_w", "Cn_w")) # The path of the Chinese file            TargetPath = "%s%s/%s"% (Todir,file,enfile.replace ("En_w", "All")) #合并文件的路径            #加载MP3文件            song1 = Audiosegment.from_mp3 (enpath)            song2 = Audiosegment.from_mp3 (cnpath)            #取得两个MP3文件的声音分贝            db1 = Song1.dbfs            DB2 = Song2.dbfs            song1 = song1[300:] #从300ms开始截取英文MP3            #调整两个MP3的声音大小 to prevent a sound from appearing large one sound small case            Dbplus = db1 -DB2            if Dbplus < 0: # song1 sounds smaller                song1+=abs (dbplus)            elif dbplus > 0: #song2的声音更小                song2+=abs ( Dbplus)            #拼接两个音频文件            song = song1 + song2            #导出音频文件            song.export (TargetPath, format= "MP3") #导出为MP3格式
