Network Audio is a combination of software, hardware and network protocols designed to deliver uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network. Developed in the 1990s, Network Audio protocols such as Cobranet is widely regarded as the first commercially successful implementation of audio over Ethernet.

Network Audio was designed for and is primarily used in large-scale audio installations (for example, convention centers, stadiums, airports, theme parks, concert halls). It is most useful in applications where a large number of audio channels must be transmitted over relatively long distances and/or to multiple locations.

An attractive alternative to traditional analog audio, Network Audio uses one audio channel for transmission per set of conductors (usually a shielded, twisted pair). Although analog audio transmission involves virtually no latency, its sound quality can be adversely affected by signal degradation due to electromagnetic interference, high-frequency loss, and voltage drop over long cable runs. Additionally, thanks to digital multiplexing, the cabling requirements of Network Audio are almost always less expensive than traditional analog audio.

Audio systems have grown significantly more advanced in recent years. Larger systems with a substantial amount of signal processing are becoming more and more common. Thus, network audio systems become more and more important which allows higher flexibility on the operation of the system. Audio sources are located in many locations and audio signals must be distributed amongst a growing number of destinations.

CobraNet is a a multi-access network, where each device is assigned with its own unique address. Any audio signal on the network can be routed to any other device on the network. One signal can simultaneously be routed to not only one output device, but to any number of output devices in the network at the same time; the network becomes an audio router in itself. This routing can be dynamically assigned. 

Because a multi-access network provides a communications channel to and from each station, all network devices can be monitored from a central point.

As a professional system designer, we would be pleased to tailor make system designs for each of our clients based on their requirement, as to achieve the best result for any budget.
