- 程序主要是求一段音频数据的基音频率 jiyinzhouqi.m --------求基音周期 find_maxn.m --------求自相关函数的最大值 test2.wav --------程序中用到的示例wav数据文件-The program is mainly the fundamental frequency for an audio data Jiyinzhouqi.m- for pitch period Find_maxn.m- the maximum

- 利用短时自相关分析的方法先求得基音周期,同时画出此时的基音周期走势图;然后对超出基音周期均值的1/5的基音周期点进行去除,再利用中值平滑方法剔除野点,同时对剔除野点后的基音周期点进行绘图,同时求得平均的基音周期。文件中附带实验语音,可验证。-By using the method of short time autocorrelation analysis first pitch is obtained, at the same time draw the pitch at this time
