实现谱减法，很实用，有四种图形显示，带颜色的，可以直接调用，需要voicebox工具包-o achieve spectral subtraction, it is practical, four graphic display, with color, you can directly call, you need the voicebox toolkit

谱减法的算法实现，可用于图像和语音信号的滤波处理，欢迎下载。-the realization of spectral subtraction algorithm, which can be used for image and audio signal processing.

语音增强算法，谱减法、小波变换以及数学形态学等的语音增强算法针对信噪比、语谱图、去噪情况，分析比较-Speech enhancement algorithm, spectral subtraction, wavelet transform and mathematical morphology speech enhancement algorithm for signal-to-noise ratio, the spectrogram denoising situation analysis

谱减法语音增强的matlab程序，读入语音信号并产生随机白噪声。-Matlab spectral subtraction speech enhancement program that reads the speech signal and generates a random white noise.
