声音信号处理示例.基本信号处理，去噪，可以加白噪声！-Examples of voice signal processing. The basic signal processing, denoising, you can add white noise!

对音频进行加噪滤波，然后比较处理性能。加高斯白噪声，不同滤波器进行滤波比较。-Adding noise to the audio filter, and then compare the processing performance. Adding Gaussian white noise, filtering comparison of different filters.

根据每帧的功率谱动态调整谱减系数,然后通过维纳滤波法把各种噪声变换为类似白噪声的噪声,最后用原减谱法把该噪声去除。-Coefficient of spectral subtraction dynamic adjustment according to the power spectrum of each frame, then all kinds of noise by Wiener filtering transform is similar to white noise, noise, an

用Burg算法求AR模型的参数。比自相关法有着较好的分辨率，但对于白噪声加正弦信号，有时可能会出现谱线分裂现象。-Algorithm for AR model parameters using the Burg. Than the autocorrelation has a better resolution, but the white noise added to sinusoidal signals, may sometimes appear as split.
