用坑函数匹配进行基音估计
he Pitch Estimation by Hole Function Matching
声音可分为乐音（浊音）和噪音（清音）两种。乐音是在短时间内近似呈现周期性的声音。在声音识别中需要测出乐音的振动频率（称为基音）。本文给出了一种坑函数匹配技术寻找频率的峰值点来进行基音的测量，取得了较好的效果，相应的C＋＋源程序也在FTP网站上给出。
Sound can divide to music sound and noise sound. The music sound is period in short time. In sound recognition, the frequency of the music sound (pitch) need to be estimated. In this paper, a technology of finding peak value point of frequency by hole function is given, and a good result is got. The C++ source code is given on a FTP network station.
