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 1):
A method for processing an audio signal, comprising:\n at a computing device having one or more processors, at least two speakers, memory, and a plurality of program modules stored in the memory and to be executed by the one or more processors:\n receiving a digital stereo audio input signal; \n extracting a middle component, a left-side component and a right-side component from the digital stereo audio input signal; \n panning the middle component into the left-side component and the right-side component, respectively; \n creating first and second copies of the middle component, wherein there is a predefined time interval between the first and second copies of the middle component; \n combining the first copy of the middle component with the left-side component into a left channel and the second copy of the middle component with the right-side component into a right channel, respectively; and \n generating a digital stereo audio output signal including the left channel and the right channel.
