三麦克风阵列，近场定位程序，采用TDOA方法，其中延时计算采用GCC方法-three mic array，nearfield location，adopt TDOA algorithm and use GCC to calculate Time Delay

用于时延的三维定位，可用，麦克风阵列最好是立体面，这样不会出现奇异值(Three dimensional positioning for time delay is available, and microphone arrays are preferably stereo surfaces, so that no singular values appear)
