基于听觉外围模型的音频基频估计方法
Fundamental frequency estimation method for audio signals based on auditory periph-eral model
摘要
Abstract
The transient components of audio signals may reduce the reliability of fundamental frequency estimation. A fundamental frequency estimation method based on auditory peripheral model is proposed in this paper. The auditory peripheral model is adopted to mimic the transduction in the auditory nerve of the inner hair cells, and a circular average magnitude difference function is used to judge the periodicity of the response of auditory nerve for estimating the funda-mental frequency of audio signals. Experimental evaluations show that the proposed method can accurately estimate the fundamental frequency of the clean audio signals. With the percussive interference in different volumes, the proposed method also achieves a lower error rate in comparison with three reference methods.关键词
