    摘要: PROBLEM TO BE SOLVED: To provide a network which maintains a constant transmission bandwidth when an acoustic signal is transmitted among a plurality of nodes. SOLUTION: In an acoustic signal processing apparatus which includes two sets of receiving I/F and transmission I/F, connects one set of receiving I/F and transmission I/F to one set of transmission I/F and receiving I/F of another processing apparatus, and constitutes a network system to transmit the acoustic signal by circulating a packet including data of the acoustic signal among the processing apparatus, the packet received by each receiving I/F is transmitted from the transmission I/F of another set when the acoustic signal processing apparatus is connected to form a loop, and the packet received by the receiving I/F of a set whose connection is not disconnected is moved to allow transmission from the transmission I/F of the same set according to the detection of the disconnection when the connection of any set is disconnected.
