In an audio network system connecting a plurality of nodes in a ring form, a master node transmits a packet of frame data regularly every sampling cycle, such that the packet circulates through the nodes during the sampling cycle. The packet is provided with a plurality of regions for containing audio sample data in correspondence to a plurality of channels. A first node reads audio sample data from a particular region of the packet, which corresponds to a particular channel allocated to the first node, and stores the read audio sample data in a buffer. The first node acquires positional information indicating whether a second node which has written the audio sample data into the particular region is located upstream or downstream of the first node. The first node reads and outputs a previous one of the audio sample data from the buffer if the second node is located upstream of the first node, and outputs a current one of the audio sample data if the second node is located downstream of the first node.
