对16bit的WindowPCM的语音文件进行压缩为4BIT的文件,压缩率约为75％,可大幅缩减所占用的空间.-The WindowPCM of 16bit audio files for 4bit compressed files, compression rate is about 75, can be substantially reduced by the space occupied.

应用背景音频情感识别实验。1）执行随机生成器程序以创建我们的训练和测试集。2）创建的实验训练set.xlxs和实验测试集的文件。3）利用实验培养set.xlxs文件将被创建，我们插入值为classifier.ccp“火车”我们的程序。4）使用实验 ；试验set.xlxs测试情感识别系统。在每一个实验的比例定位精度。关键技术计算的音频功能包括：零交叉，能量，光谱通量等。

实现音频的source filter，里面用到rtp协议的东西。推荐-achieve audio source filter, which uses rtp agreement things. Suggest

提供对标准.wav文件的解析。处理了wave文件的头部和数据段，分别读取到一个缓冲区中，并且提取出波特率、采样位数等信息。-standard of wave file analyzing.do with wave file head and data segment, reading to each cache, and pick up baud,sampling rate, etc. info.

步骤1读取wav格式音频数据（存于数组）2对数组进行分帧操作，即设定固定帧数进行分类3编写MFCC模块代码，实现MFCC参数的计算编译通过，MFCC的C++实现MFCC的特征选取，最后提取了13维左右最后结果保存在文件中

我常常使用Skype和台湾同胞还有国外的朋友进行联系，有时因为业务需要需要将语音通话录音并保留下来，在我有这个想法的那个时候（2006年）Skype官方并没有提供录音功能，咱们是做程序的嘛，没有的功能可以自己来添加啊，这也是为什么我酷爱编程的原因。 [代码性质] VC可重用代码段 -I often use Skype and Taiwan compatriots are our friends abroad to contact, and sometimes because the business needs of the need to voice recording and retained, and have this in my mind of that time (2006) Skype official did not provide recording capabilities, we are them to do the procedure, there is no function to add their own ah, this is why I love programming reasons.
