摘要 本文提出了一种综合的基音提取算法 ,综合运用了平均幅度差法、自相关函数法和简单逆滤波器跟踪法等多种算法对候选的基音频率点进行打分 ,最后再用动态搜索的算法找出一条全局最优路径。从而避免了单一方法的局限性 。 This article proposes a composite pitch extraction algorithm,which in tegrates AMDF,Autocorrelation Function and SIFT together,scores the candidate pi tch frequency,then searches for a global optimized path using dynamic programmin g.The composite algorithm abstains the limitation exists in single algorithm and shows good performance in multi-conditions.
