CobraNet® technology from Cirrus Logic is the de facto standard for delivering uncompressed networked digital audio over Ethernet networks, using standard network gear. With CobraNet technology, any audio input can be dynamically routed under software control to any audio output on the network in any combination, providing unparalleled routing flexibility. CobraNet products included royalty-based modules and royalty-free CobraNet ICs, as well as development platforms from numerous third party developers.
