Music Beat Extraction Based on Low-Pass Gaussian Filter
Zhuping Zang · 2011
A music beat extraction method based on low-pass Gaussian filter is proposed.And musical energy extraction is applied to calculate the energy envelop.Also denoise is archived by data addition in spatial domain.The quantity of data is reduced also in addition.Then,a low-pass Gaussian filter is formed to depress high frequency components and increase the prominence of low-frequency tempo information.Finally,the beat of music signal is located by peak detection calculation.The experimental results demonstrate that the proposed algorithm is capable of extracting music beat with high accuracy and it is practicable to real-time applications.
