Abstract

Stereo audio enhancement and upmixing techniques require spatial analysis of the mixture in order to work optimally for different types of contents. In this paper a method is proposed which classifies the time-frequency regions in stereo audio data into six different classes. The individual classes represent special cases of a generic stereo signal model which is introduced and characterized in the paper. Finally, the developed classifier is tested using realistic stereo audio data.
