这是YUVviewer软件的源代码，读者可以用来学习播放器的编码细节。(This is YUVviewer software source code, the reader can be used to learn the details of the encoding of the player.)

MIDI转换软件 用于MP3产生midi(MIDI to MP3 conversion software generate midi)

vc++写的网络录音机程序，录音是参照vckbase的录音api代码,结合了一小段socket(TCP)就可以用来单方说话录音了,程序分两部分一部分是(录音机+网络发送代码),一部分是(接收数据+播放波形音乐代码),由于程序只是为了自己用,很多地方没有注意错误的识别,结构也比较乱,本程序当初最头疼的就是控制损耗内存,结果用了双缓存来存储波形数据来交替的存储/清除.(vc++ program to write the network recorder, audio recording reference vckbase api code, combined with a short socket (TCP) can be Speak to unilateral recordings, and part of the program in two parts (recorder+ network to send the code), part (Receive Data+ play wave Music code form), because the program only for their own use, many places do not pay attention to the wrong identification, the structure is chaotic, the program had The most troublesome is the loss of memory control, the results with the double buffer to store the waveform data to alternate storage/removal.)
