Abstract
A device for removing crosstalk includes a jack to form an electrical connection with a plug, and an audio unit to provide a left audio channel and a right audio channel to the plug. The audio unit includes a crosstalk cancellation circuit. The crosstalk cancellation circuit estimates the crosstalk between the left audio channel and the right audio channel to obtain an estimated right-to-left crosstalk and an estimated left-to-right crosstalk, and to remove the crosstalk by subtracting the estimated right-to-left crosstalk and the estimated left-to-right crosstalk from digital signals in the left audio channel and the right audio channel, respectively.
