软件消除声音回音，适用于语音通话消除回声。代码通过将扬声器中获取的回音数据和缓存的mic语音数据通过分析比较，用特殊的算法消除回音数据，从而达到消除回声的目的。

GSM语音编码，这是一个标准C的编码，可以用于Softphone等应用，程序中有注释。-GSM voice coding, which is a standard C code that can be used in applications such as Softphone, a procedure Notes.

应用背景用于产生一个正弦扫频信号，我是用来测量声音在粮食中的衰减程度，扫频信号它与噪声的相关程度比较小，接收到的波形不易失真，所以设计了这个声音发射器。关键技术产生一个正弦扫频信号，并且扫频信号的幅值，发声时间以及起始频率和终止频率可以在前面板中进行设置，通过适当的调整便可以得到一个你所需要的声音发声器

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.

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

通过改变频率来改变音乐的音调，升调或降调都可以。另外还有移相（phaser.c)及反相(reverse.c)两个源程序文件-by changing the frequency to change the tone music, or transfer or demotion can. Another phase shifter (phaser.c) and RP (reverse.c) 2 source files
