Understanding Wireless Audio over IP

Wireless audio over IP refers to thee transmissional of audio signals over wirels network connections using standard Internet Protocol (IP) packets. Unlike traditional analogu or digital wired systems (such as AES3 or MADI), AoIP networks treat audio as data that can by routed, changed, and managed alongside eler network traffic.
