Stereo audio classification for audio enhancement

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.
