摘要
The present disclosure describes the classification of uncorrelated stereo content (hereinafter "UNCLR classification") and the cross-talk detection (hereinafter "XT ALK detection") in an input stereo sound signal. The present disclosure also describes the stereo mode selection, for example an automatic LRTD/DFT stereo mode selection. Additionally, the disclosure uses said classification so as to select one of a first stereo mode and a second stereo mode for coding a stereo sound signal including a left channel and a right channel; detect cross-talk in a stereo sound signal including a left channel and a right channel in response to features extracted from the stereo sound signal including the left and right channels; or classify of uncorrelated stereo content in a stereo sound signal including a left channel and a right channel in response to features extracted from the stereo sound signal including the left and right channels.
