摘要
本文介绍了一种改进的基于LPC逆滤波的AMDF基音提取算法——M-AMDF基音提取算法。该算法重点在预处理和后处理上下功夫以提高基音提取的准确率。我们的介绍分为两个部分,一是算法介绍,另一是对算法的评价。算法介绍的重点是预处理和后处理,对算法的评价采用了四个客观评价标准。
M-AMDF Algorithm, a modified AMDF pitch detection algorithm based on LPC liftering and foucsed on preprocessing and postprocessing, is demonstrated in this paper. Our demonstration is divided into two parts, one is the introduction of M-AMDF algorithm where preprocessing and postprocessing are emphasized the other is the estimation of the algorithm in which four object estimation criterions are adopted.
