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.(Linux platform, the blind signal separation of pure c write code. Blind signal separation algorithm based on convolution mixed, can be separated not only synthetic mixed-signal and voice signal convolution mixed in real environment can separation in the program, contains two test files can directly use the makefile after. Also worth mentioning is that the compressed bundle includes voice processing commonly used functions such as fft transform read write wav file, as well as some of the commonly used one-dimensional vector and two-dimensional matrix transform function. these can be applied directly into other applications.)
