Abstract:
A method for processing an audio signal is performed at a computing device. The method includes the following steps: receiving a digital stereo audio input signal; extracting localization cues from the digital stereo audio input signal; generating a left-side component and a right-side component from the digital stereo audio input signal, at least partially, in accordance with the localization cues; performing crosstalk cancellation to the left-side component and the right-side component, respectively, to obtain a crosstalk-cancelled left-side component and a crosstalk-cancelled right-side component; and generating a digital stereo audio output signal including the crosstalk-cancelled left-side component and the crosstalk-cancelled right-side component.

Claim (Index 2):
The method of  claim 1 , wherein the step of generating a left-side component and a right-side component from the digital stereo audio input signal further includes:\n extracting a middle component, an initial left-side component and an initial right-side component from the digital stereo audio input signal; panning the middle component into the initial left-side component and the initial right-side component, respectively, in accordance with the localization cues to obtain an intermediate left-side component and an intermediate right-side component; and upmixing a first copy of the middle component with the intermediate left-side component and a second copy of the middle component with the intermediate right-side component, respectively, to obtain the left-side component and the right-side component, wherein there is a predefined time interval between the first and second copies of the middle component.
