基于谱减法的语音降噪处理，里面有声音文件，可以直接运行观察效果-Based on the spectral subtraction speech denoising processing, there are sound files, can be run directly observed effect

信号去噪的MATLAB程序，可以参考使用，特别是故障诊断中的信号去噪-MATLAB program, the signal de-noising can refer, in particular, the signal de-noising in the fault diagnosis

有关小波的去噪程序，有阈值去噪、硬去噪、软去噪-The wavelet denoising procedures, thresholding, hard-noising, soft de-noising
