说明：  音频处理算法：语音增强技术是语音信号处理技术中的一门关键技术，本例是一种较为经典的用来估计噪声的算法程序，其实现较为简单，便于初学者学习，改程序已经通过仿真实验，并且实验结果用在方便哦的论文中。
(Speech Enhancement technology is voice signal processing technology in a key technology, in this case is a more classical algorithm used to estimate the noise, its implementation is simple, easy for beginners to learn, to change the program has been through simulation experiments, and experiments results of paper in a convenient oh)
