利用matlab语言给图像加白高斯噪音，通过高斯去燥实现图像复原-Matlab language to the image with white Gaussian noise, Gaussian to dry image restoration

可以实现对自己录制的wav格式声音进行频谱分析时域分析并且加入随机噪音，可播放声音进行对比，自动绘制波形频谱图。最后进行去噪滤波。适合大学生数字信号处理课程实验(It can realize the spectral analysis of the wav format, record the time domain analysis and add random noise. It can play the voice contras
