基于麦克风阵列用盖尔圆法进行信源数目估计。输入数据位麦克风采集的信号，阵元数目为10.-Based on microphone array，the number of sources is estimated by Gerschgrid method. Input data is obtained by microphone array and the number of array elements is 10.

通过固定波束形成算法进行语音增强的一个仿真程序，这个算法是麦克风阵列语音增强里最基本的，值得研究。-Formed by a fixed beam speech enhancement algorithm, a simulation program, this algorithm is the microphone array speech enhancement in the most basic, is worth studying.
