The pitch detection algorithm proposed by Duifhuis, Willems, and Sluyter [J. Acoust. Soc. Am. 71, 1568-1580 (1982)] can be made more than 20 times faster by replacing the harmonic sieve procedure by the approximate common denominator procedure, the results differing only slightly.
杜伊夫斯、威廉姆斯和斯勒伊特[《美国声学学会杂志》71, 1568 - 1580 (1982)]提出的基音检测算法,通过用近似公分母法取代谐波筛法,可使其速度提高20倍以上,而结果仅有细微差异。
