Poetry appreciation system(Be able to specify the folder poetry files (text files, not less than 10) in the order of eleven appreciate, the last one poem to the next song is the first poem, the first verse is the last one before a poem. User interface menu (or Command button) should at least include locate the folder, on a poem, The next poem, Exit 4. Tip: You can use DriveListBox, DirListBox and FileListBox controls.)

说明：  通过直接分析声音文件得到最大似然估计法下的混响时间和混响时间的图像，房间空间的参数来自AIR数据库，数据库里面有多种房间形式的参数形式。(Through the direct analysis of sound files, the images of reverberation time and reverberation time under the maximum likelihood estimation method are obtained. The parameters of room space come from air database, which has many kinds of room forms.)
