输入WAV文件并获取特征（*.txt）、单声道或立体声，然后按照以下步骤从WAV文件中提取特征，

豪杰解霸、Winamp等播放软件中都有频谱分析仪。我们有时在编写一个多媒体软件时，总想实现这种功能，然而在网上介绍这方面的却比较少，现在用VB做了一个。希望对编程有所帮助。有些地方不完善，请大家提出意见。

在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用. 另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.-in linux platform, net write c Blind Signal Separation code. it is based on convolution of mixed Blind Signal Separation algorithm, not only can be separated from the artificial synthesis of mixed-signal, but for the real environment convolution of mixed voice signals can be separated. in this procedure, the tests included two documents, makefile can be used directly after. Also worth mentioning is that Compression bag containing some of voice processing functions commonly used. fft transform, for example, to read write wav file, and some of the commonly used one-dimensional and two-dimensional vector matrix transformation functions. these can be directly applied to other applications going.

自适应线性预测器，采用FIR滤波器实现。-adaptive linear predictor, the use of FIR filters achieve.
