摘要
详细分析了音高检测的原理,并通过Matlab的实验验证,比较了5种检测方法的优缺点,并在此基础上讨论了音高检测精度的问题,最后给出了具有较高检测精度的改进型FFT频域分析法。
The principle of pitch detection is analysed and the precision of pitch detection is discussed. The advantages and disadvantages of five kinds of detecting methods are given through the computer simulating results. Finally, the improved pitch deteting method and embedded electronic composition scheme of tuning device are given.
