Setting up an AES67-compliant audio network in your studio ensures high-quality, synchronized audio over IP. This guide walks you through each step to create a reliable and scalable audio-over-IP system that meets AES67 standards.
Understanding AES67 and Its Benefits
AES67 is a technical standard for audio-over-IP interoperability developed by the Audio Engineering Society. It allows different manufacturers’ equipment to communicate seamlessly, providing flexibility and future-proofing your studio’s infrastructure.
Prerequisites and Equipment Needed
- Network switches supporting IEEE 802.1Q (VLAN) and IGMP snooping
- Audio interfaces and devices compatible with AES67 or Ravenna/Livewire/AES67 standards
- Properly configured IP addresses for all devices
- Network management software
- Basic knowledge of IP networking and audio routing
Step 1: Network Planning
Begin by designing your network topology. Use a dedicated, managed switch network to minimize latency and interference. Assign static IP addresses to all devices to ensure stable communication.
Creating VLANs for Audio Traffic
Configure VLANs on your switches to segregate audio traffic from other network data. This improves performance and security. Assign each device to the appropriate VLAN.
Step 2: Configuring Devices
Ensure all audio devices support AES67 or are compatible with a protocol that does. Update firmware if necessary. Set each device’s IP address, subnet mask, and gateway according to your network plan.
Synchronizing Devices
Configure Precision Time Protocol (PTP) on your network to synchronize all devices precisely. Enable PTP on switches and devices that support IEEE 1588 to maintain tight synchronization essential for AES67.
Step 3: Testing the Network
Use network testing tools to verify connectivity, latency, and packet loss. Confirm that all devices are visible on the network and can communicate with each other.
Play test audio from one device and check if it is received correctly on others. Adjust configurations as needed to optimize performance.
Step 4: Routing and Management
Set up audio routing within your digital audio workstation (DAW) or control software. Use network management tools to monitor traffic and troubleshoot issues promptly.
Conclusion
Creating an AES67-compliant audio network involves careful planning, configuration, and testing. By following these steps, you can ensure high-quality, synchronized audio across your studio, enabling more flexible and reliable production workflows.
