小波降噪，针对语音信号，包括小波变换的分解和重构- wavletDenoising for WAV voice,including wavlet decompress and recompress.

奇异谱分解matlab代码，对信号信息特征值分解，得到不同特征向量的子序列，筛选主要权重的子序列进行重构，平滑原始型号，起到降噪和过滤的作用。(The singular spectrum decomposes the matlab code, decomposes the eigenvalues of the signal information, obtains subsequences of different eigenvectors, filters the sub-sequences
