Audio-over-IP technology has transformed how audio is transmitted in professional settings, offering greater flexibility and scalability. Two prominent protocols in this domain are AES67 and AVB. Understanding their differences is crucial for selecting the best option for your setup.
What is AES67?
AES67 is an open standard developed by the Audio Engineering Society. It enables interoperability between different audio-over-IP systems, regardless of manufacturer. AES67 is designed for high-performance, low-latency audio streaming over IP networks, making it popular in broadcasting and live sound environments.
What is AVB?
AVB, or Audio Video Bridging, is a set of IEEE standards that facilitate real-time audio and video transmission over Ethernet networks. It is widely adopted in professional audio installations, providing deterministic data transfer with strict timing requirements. AVB is often integrated into managed network switches for optimal performance.
Performance Comparison
Interoperability
AES67’s open standard ensures broad compatibility across different devices and manufacturers. In contrast, AVB is more dependent on specific hardware and network configurations, which can limit interoperability.
Latency and Timing
Both protocols are designed for low latency, but AVB’s deterministic nature often results in more predictable timing. AES67 can achieve low latency as well, but its performance may vary depending on network conditions.
Network Requirements
AVB requires managed switches supporting IEEE standards, which can add to infrastructure costs. AES67 operates over standard Ethernet networks, making it easier to implement without specialized hardware.
Which Protocol Is Better for Your Setup?
The choice between AES67 and AVB depends on your specific needs. If interoperability and flexibility are priorities, AES67 is a strong choice. For applications demanding strict timing and real-time performance, AVB may be more suitable.
- AES67: Best for open systems and broad compatibility.
- AVB: Ideal for fixed, managed network environments requiring deterministic timing.
Evaluating your network infrastructure, budget, and performance requirements will help determine the best protocol for your professional audio setup.
