Patent ID: 7688989

Claim:
A method, executing on hardware, for processing sound signals for a surround left channel (S L ) and a surround right channel (S R ), comprising the steps of: generating a continually varying delay between the signals of the surround right channel (S R ) and the surround left channel (S L ), wherein the continually varying delay decorrelates the surround left channel (S L ) and the surround right channel (S R ), and wherein the continually varying delay varies over time so as not to have a fixed value; processing the signals of the surround left channel (S L ), wherein processing of the signals of the surround left channel (S L ) includes the step of introducing a first delay to the signals of the surround left channel (S L ); and processing the signals of the surround right channel (S R ), wherein processing of the signals of the surround right channel (S R ) includes the step of introducing a second delay to the signals of the surround right channel (S R ), wherein the first delay and the second delay provide the continually varying delay between the signals of the surround right channel (S R ) and the surround left channel (S L ).
