US 2016/0007135 A1 · AUDIO CHANNEL CONTROL CIRCUIT

Abstract

An audio channel control circuit includes a filter module and a determining module. The audio channel control circuit receives a first audio signal and a second audio signal from an audio device. The first audio signal loads a first carrier signal, while the second audio signal loads a second carrier signal. The first carrier signal and the second carrier signal have different phases. The filter module filters the first audio signal and the second audio signal, separating the first carrier signal from the first audio signal and the second carrier signal from the second audio signal. According to the phases of the first carrier signal and the second carrier signal, the determining module chooses a speaker of the left audio channel or a speaker of the right audio channel to output the first audio signal or the second audio signal.
