过零率(Zero Crossing Rate)是在每个音框中,音讯通过零点的次数,具有如下特性: 1.一般而言,杂讯的过零大于气音的过零率,而气音的过零率又大于有声音的过零率 2.通常在断点侦测,估测气音的起始位置和结束位置 3.可用来预估信号的基频,但很容易出错,所以必须先进行前处理 以下显示如何计算过零率 范例1输入:...

Zero-crossing rateJerome Sueur
rate= zerocrossrate(TT)returns the zero-crossing rate of the data stored in the MATLAB®timetableTT. IfTTcontains multiple channels, then the function analyzes each channel independently. example rate= zerocrossrate(___,Name,Value)specifies additional name-value arguments. Use this syntax with ...
