Apparatus and Method for Sound Stage Enhancement

摘要

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.

1. A non-transitory computer readable storage medium with instructions executable by a processor to:
identify a center component, a side component and an ambient component within right and left channels of a digital audio input signal; determine a spatial ratio from the center component and side component; adjust the digital audio input signal based upon the spatial ratio to form a pre-processed signal; perform recursive crosstalk cancellation processing on the pre-processed signal to form a crosstalk cancelled signal; and realign the center component of the crosstalk cancelled signal.
