针对宽带语音信号，采用ISM算法进行波束形成-For wideband speech signal, beamforming algorithm using ISM

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.
