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 6):
The method of  claim 2 , wherein the digital stereo audio input signal further includes a left signal and a right signal, the step of 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 further includes:\n applying a left amplitude panning parameter and a right amplitude panning parameter to the middle component, respectively, to obtain an initial mid-left component and an initial mid-right component; determining an interaural time difference (ITD) and an interaural intensity difference (IID) between the left signal and the right signal; applying the ITD and the IID to at least one of the initial mid-left component and the initial mid-right component to obtain an intermediate mid-left component and an intermediate mid-right component; and combining the initial left-side component with the intermediate mid-left component and the initial right-side component with the intermediate mid-right component, respectively, to obtain the intermediate left-side component and the intermediate right-side component.
