PROBLEM TO BE SOLVED: To provide a technology for correcting sample deviation so that a signal inputted with an absolute time is outputted from all nodes at the same sampling time regardless of the position relationship of the nodes when transmitting audio sample data while circulating a packet in an annular audio network system. SOLUTION: When an own node reads audio sample data of a channel to be read from the packet, the sample data read at a current sampling period and those read before one sampling period are stored into a buffer. When the sample data of the buffer are outputted to the outside, the sample data before one sampling period and those of the current sampling period are read and outputted when the node, where the sample data of the channel are put on the packet, exists upstream and downstream, respectively.
