- Interfaces & Soundcards

CobraNet is a technology from Cirrus Logic that provides distribution of isochronous digital audio, control and monitoring data over Ethernet. CobraNet operates at the Data Link Layer also referred to as OSI Layer 2 or MAC layer.  Note that in most cases CobraNet can coexist with regular data on an Ethernet network, because CobraNet packets are just regular Ethernet packets that have a CobraNet identifier.

To learn more about CobraNet, see Cirrus Logic's CobraNet website and the Wikipedia CobraNet page.

AudioScience has developed the ASI6416, ASI54xx, ASI6316, and ASI53xx CobraNet sound cards as well as the ASI2416 1RU and the ASI2202 CobraNet interfaces.  The ASI6416, ASI54xx, and ASI6316 look just like regular AudioScience sound cards to software applications, allowing multiple streams of audio to be played and recorded to/from the network.  The ASI2416 allows audio equipment to be interfaced to the CobraNet network.  It can be configured with analog and/or AES/EBU I/O as well as GPIO for control and monitoring.

ASIControl is a software application that can be used to set up the routing of audio streams between any CobraNet device on the network (not just AudioScience products).
