Audio system and audio apparatus and channel mapping method thereof

摘要

An audio system, and an audio apparatus and a channel mapping method thereof are provided. The audio apparatus includes a interface configured to receive a plurality of test tone signals from each of a plurality of sound output apparatuses configured to output multichannel audio signals, a channel determiner configured to analyze the plurality of test tone signals determine locations of the plurality of sound output apparatuses, and generate a determination result based on the determined locations, an switch configured to output one test tone to each of the plurality of sound output apparatuses, and perform channel mapping to map channels through which the multichannel audio signals are output according to the determination result, and an output unit configured to be randomly connected to the plurality of sound output apparatuses, and output the multichannel audio signals by adjusting the random connection according to the channel mapping.
