光谱预处理源程序2

TXT信号的获取：一般都是拿到一个.WAV的信号，用cooledit或者其他的打开，另存为txt格式，注意的是，此时txt文件的前面两行会写入一些采样率的信息，将这几行删掉，程序就可以顺利得读取你保存的txt了。(TXT signal acquisition: generally get a .WAV signal, with coolit or other open, save as txt format, note that at this time txt file in front of two lines will write some sampling rate information, will These lines deleted, the program can be smooth to read your saved txt.)

可以对处理后的语音进行一个客观上的评判，提供客观评价因子。(It is possible to make an objective evaluation of the processed speech and provide an objective evaluation factor.)

频域归一化的自适应滤波消除回声，效果非常不错(Frequency domain normalization of adaptive filtering to eliminate echo, the effect is very good )

很经典的MELP的MATLAB算法仿真。从一个外国网站上下载，很棒(MELP is the classic algorithm of the MATLAB simulation. From a foreign website, great)

这里主要是压缩感知的贪婪算法，通过OMP来实现DOA的估计，主要应用在阵列信号处理领域。(Here compressed sensing greedy algorithm OMP, the main application in the field of array signal processing to achieve the DOA estimates.)

g.729编解码源代码，已经在freescale的处理器上面实现。(G.729 codec source code, has been in the Freescale processors to achieve the above.)
