代码说明：

说明：傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)

下载说明：请别用迅雷下载，失败请重下，重下不扣分！
