CobraNet 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, CobraNet is widely regarded as the first commercially successful audio-over-Ethernet implementation.
CobraNet was designed for and is primarily used in large commercial audio installations such as convention centers, stadiums, airports, theme parks, and concert halls.
It has applications where a large number of audio channels must be transmitted over long distances or to multiple locations.
CobraNet is an alternative to analog audio, which suffers from signal degradation over long cable runs due to electromagnetic interference, high-frequency attenuation, and voltage drop.
Additionally, the use of digital multiplexing allows audio to be transmitted using less cabling than analog audio.
CobraNet was developed in 1996 by Boulder, Colorado-based Peak Audio.
Initial demonstrations were of a 10 Mbit/s point-to-point system with limited channel capacity.
The first permanent installation of CobraNet in this early form was to provide background music throughout Disney's Animal Kingdom theme park.
The first commercial use of CobraNet was during the halftime show at Super Bowl XXXI in 1997.
CobraNet was first introduced as an interoperable standard in collaboration with manufacturer QSC Audio Products.
QSC was the first to license the technology from Peak Audio and marketed it under the RAVE brand.
At this point CobraNet had graduated to fast Ethernet and used a unique collision avoidance technique to carry up to 64 channels per Ethernet collision domain.
CobraNet was subsequently enhanced to support and eventually require a switched Ethernet network.
An SNMP agent was added for remote control and monitoring.
