摘要

为了克服目前诸多基音周期检测算法迟延较大的缺点

本文提出了一种基音周期的实时检测算法.实验结果表明:该算法可在当前帧内实时提取精确的基音周期估计值

减少了传统的自相关基音检测算法因平滑处理而带来的编码迟延.

Abstract

A real time pitch detection scheme is proposed in this paper in order to reduce the delay of the existent pitch detection algorithms. The experimental results show that the new scheme can obtain exact pitch level within the current frame and reduce the delay of the existent auto-correlation pitch detection algorithms using smooth processing.
