Abstract
An audio system includes a first audio apparatus that receives a first audio signal with a first number of channels and a second audio apparatus connected to the first audio apparatus via a network. The first audio apparatus includes a signal processing unit configured to generate, on the basis of the first audio signal received from the outside of the first audio apparatus, a second audio signal with a second number of channels larger than the first number of channels, and a communication unit configured to transmit a third audio signal corresponding to a part of the channels in the second audio signal generated by the signal processing unit to the second audio apparatus.
