Abstract

In analyzing audio material for features useful for extractingcontent, we must consider the value gained by adapting our analysis algorithms to the analysis processes of the human ear. This aspect with regard to loudness features is thoroughly examined in this paper. The increase in correlation to be gained by such cognitive processing is about 10%.
