ZoomFFT

本程序是基于分离谱算法的最小值选中次数加权算法的MATLAB源代码,可以对一维信号先进行谱分离,然后再在最小值的基础上对信号进行重建.(This procedure is based on the sub-out algorithm to select the minimum number of weighted algorithm MATLAB source code, can be conducted one-dimensional spectral signal separation, then the minimum value based on the signal reconstruction.)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)
