CobraNet

CobraNet is a digital audio networking technology developed by Peak Audio (later acquired by Cirrus Logic). It uses standard Ethernet infrastructure to transmit multiple channels of high-quality audio over a local area network (LAN). CobraNet is often used in professional audio and commercial sound installations, allowing for the distribution of audio signals to multiple locations without the need for bulky analog cabling.

Key Features:

• Digital Audio Transmission: CobraNet transmits audio signals in a digital format, providing improved audio quality compared to analog transmission methods.
• Ethernet Based: It leverages existing Ethernet networks, reducing the need for dedicated cabling infrastructure.
• Multiple Channels: CobraNet supports the transmission of multiple audio channels simultaneously, accommodating complex audio routing requirements.
• Scalability: CobraNet networks can be scaled to accommodate a wide range of applications, from small installations to large venues.
• Deterministic Latency: The technology offers relatively low and predictable latency, which is critical for live sound and other time-sensitive applications.
• Centralized Management: CobraNet networks are typically managed through software applications that allow for configuration, monitoring, and troubleshooting.

Applications:

CobraNet has been used in various applications, including:

• Live Sound Reinforcement: Distributing audio signals to multiple speakers and amplifiers in concert venues.
• Commercial Audio Systems: Managing audio distribution in shopping malls, airports, and other public spaces.
• Broadcast Studios: Routing audio signals between studios and control rooms.
• Recording Studios: Interconnecting recording equipment and monitoring systems.
• Audio Distribution in Educational Facilities: Distributing audio throughout schools and universities.

History:

CobraNet was introduced in the late 1990s and gained popularity as a cost-effective and flexible solution for digital audio networking. While newer technologies like Dante and AVB have emerged, CobraNet remains in use in many existing installations. Cirrus Logic discontinued the licensing and support of CobraNet in 2016, impacting its long-term viability in new installations.

Alternatives:

Several alternative technologies exist for digital audio networking, including:

• Dante (Digital Audio Network Through Ethernet)
• AVB (Audio Video Bridging) / TSN (Time-Sensitive Networking)
• EtherSound
• AES67
