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.

Abstract: A non-transitory computer readable storage medium with instructions executable by a processor identify a center component, a side component and an ambient component within right and left channels of a digital audio input signal. A spatial ratio is determined from the center component and side component. The digital audio input signal is adjusted based upon the spatial ratio to form a pre-processed signal. Recursive crosstalk cancellation processing is performed on the pre-processed signal to form a crosstalk cancelled. The center component of the crosstalk cancelled signal is realigned to create the final digital audio output.
Abstract translation: 具有可由处理器执行的指令的非瞬时计算机可读存储介质识别数字音频输入信号的左和右声道内的中心分量，侧分量和环境分量。 从中心分量和侧分量确定空间比。 数字音频输入信号根据空间比进行调整，形成预处理信号。 对预处理的信号执行递归串扰消除处理以形成串扰消除。 串扰消除信号的中心分量重新对准以产生最终的数字音频输出。
