Patent ID: 7974418

Claim:
A method of audio signal cross-talk cancellation, comprising the steps of: (a) summing left channel and right channel input signals and attenuating said sum; (b) differencing said left channel and right channel input signals and filtering said difference with a filter having a transfer function 1/S 0 (e jω ) where S 0 (e jω )=H 1 (e jω )−H 2 (e jω ) with H 1 (e jω ) and H 2 (e jω ) are head-related transfer functions, wherein H 1 , H 2 relate to the location of two real speakers and a directional component S 0 , wherein S 0 =H 1 −H 2 ; and (c) outputting as a first channel the sum of the results of steps (a) and (b); and (d) outputting as a second channel the difference of the results of said steps (a) and (b).
