Fig. 3From: An audio attention computational model based on information entropy of two channels and exponential moving averageAn illustration of waveform and attention graph of signal 1. The region marked in red is the area of interest and marked in orange is the non-interest area in d. In contrast to Kayser model which extracts contrast characters from the spectrum of audio signal in multi-scale, the proposed attention model based on information entropy and exponential moving average smooth reflects the value change of audio attention in the time domainBack to article page
