用短时平均能量值对干净的语音信号进行检测，可以区分语音和非语音部分(With short time average energy value to test the clean speech signal, can distinguish between voice and non-voice part )

数学建模中常用的图论程序，经整理，有注释(Commonly used mathematical modeling of graph theory program, collated, annotated)

说明：  MUSIC算法是最经典的超分辨DOA估计方法，它利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA。MUSIC算法对DOA的估计从理论上可以有任意高的分辨率(MUSIC algorithm is the most classical super-resolution DOA estimation method. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectral function, and detects the DOA of signal through peak search. MUSIC algorithm can theoretically estimate DOA with arbitrary high resolution.)
