Introduction
When it comes to professional audio networking, you might have heard about AES67 and Dante. Both are popular standards that help transmit audio over IP networks, but they serve different purposes and have unique features. If you’re setting up an audio system or upgrading your network, understanding these two can save you time and money.
In this article, I’ll walk you through the key differences between AES67 and Dante. You’ll learn how each works, their benefits, and when to choose one over the other. By the end, you’ll feel confident picking the right audio networking solution for your setup.
What Is AES67?
AES67 is an open standard for audio-over-IP interoperability. It was developed by the Audio Engineering Society to ensure different audio devices can communicate over IP networks, even if they use different proprietary protocols.
AES67 focuses on basic audio streaming features like synchronization, clocking, and transport. It uses standard protocols such as RTP (Real-time Transport Protocol) and PTP (Precision Time Protocol) to deliver high-quality, low-latency audio.
Key Features of AES67
- Open Standard: AES67 is royalty-free and designed for interoperability.
- Low Latency: Supports audio streaming with minimal delay.
- Clock Synchronization: Uses IEEE 1588 PTP for precise timing.
- Compatibility: Works with various IP networks and devices.
- Basic Audio Transport: Focuses on uncompressed PCM audio streams.
AES67 is widely adopted in broadcast and professional audio environments where devices from different manufacturers need to work together seamlessly.
What Is Dante?
Dante is a proprietary audio-over-IP networking technology developed by Audinate. It has become a leading solution for digital audio distribution in live sound, recording studios, and installations.
Dante offers a complete ecosystem including hardware, software, and management tools. It supports hundreds of audio channels over standard Ethernet networks with very low latency and high reliability.
Key Features of Dante
- Proprietary Technology: Owned by Audinate, requires licensing.
- High Channel Count: Supports hundreds of simultaneous audio streams.
- Low Latency: Typically under 1 millisecond.
- Easy Setup: User-friendly software for device discovery and routing.
- Integrated Clocking: Built-in synchronization without extra configuration.
- Redundancy: Supports network failover for reliability.
Dante is popular for its plug-and-play nature and extensive device compatibility within its ecosystem.
AES67 vs Dante: Technical Comparison
Understanding the technical differences helps you decide which protocol fits your needs.
| Feature | AES67 | Dante |
| Type | Open standard | Proprietary |
| Audio Channels | Limited by network and device | Hundreds |
| Latency | Low (typically 1-2 ms) | Very low (under 1 ms) |
| Clock Synchronization | IEEE 1588 PTP | Integrated, automatic |
| Interoperability | High (multi-vendor) | Limited to Dante-enabled gear |
| Setup Complexity | Requires manual configuration | User-friendly software tools |
| Network Requirements | Standard IP networks | Standard IP with QoS support |
| Licensing | Free | Paid license required |
Latency and Synchronization
Dante’s integrated clocking system ensures ultra-low latency and tight synchronization without extra setup. AES67 relies on PTP for synchronization, which can be more complex to configure but offers excellent timing accuracy.
Interoperability
AES67 was designed to bridge different audio-over-IP systems. It allows devices from various manufacturers to exchange audio streams. Dante devices can support AES67 streams, but full interoperability depends on firmware and software updates.
When to Use AES67
AES67 is ideal if you want an open, vendor-neutral solution. It’s perfect for:
- Broadcast Facilities: Where equipment from multiple brands must work together.
- Large Installations: That require interoperability between different audio networks.
- Cost-Sensitive Projects: Since AES67 is royalty-free.
- Future-Proofing: Open standards tend to have longer support.
However, AES67 may require more network expertise to set up and manage, especially for clock synchronization and stream routing.
When to Use Dante
Dante is best if you want a turnkey solution with easy setup and extensive device support. It suits:
- Live Sound and Events: Where quick deployment and reliability are critical.
- Recording Studios: For high channel counts and low latency.
- Installations with Dante Ecosystem: When using Dante-enabled hardware.
- Users Who Prefer Software Tools: For managing audio routing and monitoring.
The main downside is licensing costs and being tied to Audinate’s ecosystem.
AES67 and Dante Interoperability
In recent years, Audinate has added AES67 support to Dante devices. This means you can route AES67 streams to and from Dante networks, improving flexibility.
How Interoperability Works
- Dante devices can send and receive AES67 streams.
- AES67 streams use standard RTP packets, which Dante can interpret.
- Some Dante features like device discovery and control are not available with AES67 streams.
- Proper network configuration is essential to ensure smooth interoperability.
This hybrid approach lets you mix open and proprietary systems, giving you the best of both worlds.
Network Considerations for AES67 and Dante
Both AES67 and Dante run on standard IP networks, but there are some differences in network setup.
AES67 Network Tips
- Use switches that support IEEE 1588 PTP for clock synchronization.
- Configure Quality of Service (QoS) to prioritize audio packets.
- Plan for multicast traffic, as AES67 uses multicast for audio streams.
- Monitor network latency and jitter to maintain audio quality.
Dante Network Tips
- Dante works well on standard gigabit Ethernet.
- Use managed switches with QoS to ensure low latency.
- Dante supports redundancy with dual networks for failover.
- Use Audinate’s Dante Controller software for easy device management.
Proper network design is crucial for both protocols to avoid audio dropouts and latency issues.
Cost Comparison
Cost is an important factor when choosing between AES67 and Dante.
| Cost Factor | AES67 | Dante |
| Licensing Fees | None | Licensing fees apply |
| Hardware Costs | Depends on manufacturer | Dante-enabled devices may cost more |
| Software Tools | Often free or open-source | Dante Controller is free, but ecosystem tools may cost |
| Training & Setup | May require more technical skill | Easier setup reduces labor costs |
AES67 can be more cost-effective for large, multi-vendor systems. Dante’s ease of use and reliability may justify higher upfront costs for many users.
Future Trends in Audio Networking
The audio networking landscape continues to evolve. Here’s what to watch for:
- Increased AES67 Adoption: More manufacturers are adding AES67 support to improve interoperability.
- Dante Expanding Features: Audinate is enhancing Dante with better AES67 compatibility and cloud-based management.
- New Standards: Emerging protocols like RAVENNA and Livewire+ also support AES67, broadening options.
- Network Improvements: Advances in IP infrastructure will reduce latency and improve reliability.
- Hybrid Systems: Combining AES67 and Dante will become more common in complex installations.
Staying informed about these trends will help you future-proof your audio network.
Conclusion
AES67 and Dante are both powerful audio-over-IP solutions, but they serve different needs. AES67 offers an open, interoperable standard ideal for multi-vendor environments and cost-conscious projects. Dante provides a polished, user-friendly ecosystem with high channel counts and ultra-low latency, perfect for live sound and studio applications.
Choosing between them depends on your priorities: openness and flexibility versus ease of use and ecosystem support. Thanks to growing interoperability, you can even combine AES67 and Dante devices to build a versatile audio network. Understanding these differences helps you make the best choice for your audio setup.
