actual pitch meaning in Chinese

实际节距,实际螺距
实螺距

In order to overcome the disadvantages of low accuracy , high complexity , and lack of robustness in many actual pitch detection algorithms , a new algorithm for pitch detection on the basis of local modulus maxima of dyadic wavelet transform was presented
摘要为了克服目前诸多基音周期检测算法精度低、计算复杂度高、鲁棒性差的缺点，研究了一种采用二进小波变换模极大值进行基音周期检测的算法。
