Abstract
In this paper, by the analysis of auditory filter, we propose a new method of calculation of SNR of audio. The method firstly makes the analysis of correlation of audio, then separates and refines the stream of harmonic wave according to auditory stream in computational auditory scene analysis (CASA), lastly, computes the SNR. As taking into account the auditory feature of people fully, it inosculates subjective feeling of people well. The experiment indicates it can compute the SNR of audio accurately.
