Directsound列举所有音频设备VB开发

在信号处理中，通常需要把采集信号的实时波形显示出来。 如果直接在屏幕上动态绘图的话，会出现闪烁现象，为了克服这个问题，本文采用的就是先在内存绘图，然后再拷贝到屏幕，从而实现动态绘图而不闪烁。-In signal processing, usually need to collect real-time waveform signal is displayed. If the direct dynamic graphics on the screen, then there will be blinking phenomenon, in order to overcome this problem, this paper is the first graphics memory, and then copied to the screen in order to achieve dynamic graphics without blinking.

音节中心音的检测。输入为帧级别的特征，每一帧有多于12维特征；检测十二平均律在该首音乐上的中心音。-Tone syllable center detection. Input for the frame-level features, each frame has more than 12-dimensional features detection十二平均律in the center of the first music on the sound.

万年历时钟,有万年历,也有时钟,可设置闹钟-hefty almanac clock, a hefty almanac, a clock, alarm clock can be set

计算高斯混合模型先验概率和后验概率的程序，采用大矩阵运算，大大提高了运行速度。-Gaussian mixture model calculated a priori probability and the probability of post-mortem procedures, using a large matrix computation, greatly improved speed.

1,增加了歌词搜索的自主性,用户可以选择自定义搜索关键字,也可以自定义是否和歌词文件相关联,这里的关联并不是把歌词写入歌曲文件,而是在程序中建立一种关联,以免每次播放这首歌的时候都去搜索歌词,而是直接去读取关联好的歌词文件. 2,增加了指定歌词的搜索目录,指定歌词的保存目录功能.为了性能考虑,歌词的搜索目录不会往下递归,只搜索设置的那一级目录. -1, an increase of the autonomy of the lyrics search, the user can select a custom search keyword, but also can customize it and lyrics files, link here is not to write songs lyrics files, but in the process of establishing a linked so as not to play this song every time the time to search for the lyrics, but a direct link to read the lyrics a good document. 2, an increase of the designated search lyrics directory, specify the directory function of the preservation of the lyrics. to performance considerations, the lyrics search directory recursion is not down, it only set up a search directory.

Media Player Classical-Audio player是一个基于Mplayer2控件的音频播放器（视频也可以播放，但是...），所有Mplayer2支持的文件格式本程序都支持。本程序的一大特色是漂亮的播放列表（位于左下角）。所有的列表都保存在“曲目列表”文件夹中，你若愿意可以手动编辑。-Media Player Classical-Audio player is a Mplayer2 controls on the audio player (also can play video, but ...), Mplayer2 support all file formats supported this process.
