Audio over IP (AoIP) has become the backbone of modern audio networking, replacing traditional point-to-point analog and digital infrastructure with flexible, scalable, and cost-effective IP-based solutions. In broadcast, live sound, and professional AV environments, three names dominate the conversation: Dante, Ravenna, and WheatNet-IP. Each platform offers distinct philosophies, technical approaches, and ecosystem advantages. Choosing the right one can simplify your workflow, reduce latency, and future-proof your investment. This expanded comparison will help you evaluate which AoIP solution aligns best with your operational needs, technical expertise, and budget.

Overview of the Three AoIP Solutions

Before diving into technical details, it's essential to understand the origin, governance, and core design principles of each technology. While all three transport high-quality digital audio over standard Ethernet networks, their architectures differ significantly.

Dante

Developed and maintained by Audinate, Dante is the most widely adopted AoIP protocol in the live sound, installed sound, and broadcast markets. Its strength lies in simplicity: plug a Dante-enabled device into a network, and it is automatically discovered and routable via Dante Controller software. Dante supports up to 512x512 audio channels on a 1 Gbps network (or higher with redundant networks), with extremely low latency (as low as 250 microseconds). The ecosystem includes thousands of certified products from over 500 manufacturers, making it a safe choice for multi-vendor environments. Dante uses a proprietary implementation of IEEE 1588 Precision Time Protocol (PTP) for synchronization, which works seamlessly within its own domain but can require careful planning when bridging to other clock domains.

Ravenna

Ravenna is an open standards-based AoIP solution originally developed by ALC NetworX and later made royalty-free. It is now managed by the AVnu Alliance as part of the Milan protocol family. Ravenna is built on standard Ethernet QoS features and uses IEEE 1588-2008 (PTPv2) with a profile optimized for professional media. Its open architecture allows for deep interoperability with other AVB (Audio Video Bridging) and AES67-compatible devices. Ravenna is particularly strong in large-scale installations such as broadcast plants, concert halls, and multi-purpose venues where hundreds or thousands of audio channels must be routed across multiple subnets. It offers flexible redundancy options, including SMPTE ST 2022-7 seamless protection switching. However, setup requires a higher level of network expertise compared to Dante.

WheatNet-IP

WheatNet-IP is the proprietary AoIP solution from Wheatstone, designed primarily for broadcast radio and television facilities. It integrates deeply with Wheatstone consoles, routing matrices, and processing gear, offering a unified control surface for audio routing, mixing, and monitoring. WheatNet-IP uses a switched Ethernet architecture with its own discovery protocol (WheatNet-IP Control Protocol) and supports AES67 for interoperability with third-party devices. Key differentiators include the Blade architecture, where each Blade handles I/O and processing, and the intuitive WheatNet-IP Navigator software for drag-and-drop routing. Latency is low, typically below 1 millisecond, and the system scales well for medium to large broadcast facilities. The downside: ecosystem lock-in — maximum benefit comes from using Wheatstone endpoints, which can be a limitation for facilities that prefer multi-vendor sourcing.

Technical Comparison

All three solutions deliver high-quality, low-latency digital audio, but differences in network protocol, synchronization, and management can affect performance and ease of deployment.

Network Protocols and Standards

Dante uses a proprietary transport layer that is not directly compatible with standard AVB or AES67 without additional bridging (though Dante supports AES67 via Dante Domain Manager). Its discovery and routing rely on Audinate's own protocols, which operate efficiently within a dedicated Dante network but can pose challenges when mixing with other IP traffic.
Ravenna is built on standard IP protocols (RTP, UDP, PTPv2) and fully supports AES67, making it inherently interoperable with other AES67-compliant devices. Ravenna also aligns with the Milan standard for deterministic performance in professional AV environments.
WheatNet-IP uses proprietary control and audio transport, but includes AES67 support since firmware version 4.0, enabling basic interoperability with Dante and Ravenna systems. However, advanced features like redundant streams and automatic discovery remain within the Wheatstone ecosystem.

Synchronization and Latency

All three rely on IEEE 1588 PTP, but with different profiles and implementations. Dante uses a proprietary PTP profile (Dante PTP) optimized for its own devices, achieving sub-millisecond latencies even in large networks. Ravenna uses standard PTPv2 with a media profile, allowing synchronization with diverse PTP-aware devices, but requires careful clock domain management. WheatNet-IP uses its own synchronization method (Blade clocking) that can also be locked to an external PTP grandmaster. In terms of raw latency, Dante offers the lowest typical round-trip times (down to 0.25 ms), while Ravenna and WheatNet-IP generally achieve 0.5–1 ms in most configurations.

Scalability and Channel Count

Dante's maximum channel count per link is 512x512 on 1 Gbps, and it supports up to 256 Dante devices in a single network (using Domain Manager for larger topologies). Ravenna scales much higher: with proper QoS and network design, thousands of channels can be distributed across multiple switches without significant degradation. Ravenna is the go-to choice for large broadcast plants with hundreds of studios. WheatNet-IP scales to 256 Blades (each Blade typically provides 8–64 channels), supporting roughly 2,000 audio paths in a fully loaded facility. For most broadcasters, that is more than sufficient.

Management and Configuration

Dante's Dante Controller is perhaps the most user-friendly AoIP management software on the market. It automatically discovers all Dante devices on the subnet, displays signal flow in a matrix, and allows drag-and-drop routing. No dedicated network administrator is required for small to medium networks. Ravenna management varies by manufacturer; tools like Lawo's Ravenna Manager or direct integration into mixing console software offer powerful control but come with a steeper learning curve. WheatNet-IP's Navigator software provides an intuitive visual interface for patching and system monitoring, tailored to broadcast workflows. It also includes built-in SNMP support for integration with existing facility monitoring systems.

Device Ecosystem and Interoperability

Ecosystem breadth is often the deciding factor for AoIP adoption. Dante boasts over 3,000 certified products from more than 500 brands, including mixing consoles, amplifiers, speakers, intercoms, and converters. This makes Dante the easiest to implement in a multi-vendor environment — you can mix a Yamaha console with a Shure wireless system and a QSC amplifier without any gateway, as long as all devices are Dante-equipped.

Ravenna's ecosystem is smaller but includes high-end broadcast manufacturers like Lawo, Neumann, and directOut. Ravenna's adherence to open standards also means that any AES67 device can be integrated, though AES67 offers only a subset of the full Ravenna feature set (e.g., no automatic discovery or advanced redundancy).

WheatNet-IP is heavily tied to Wheatstone hardware. While third-party AES67 devices can be connected, they lose full control depth — for example, remote gain control or monitoring may not be available. However, for facilities already invested in Wheatstone consoles (like the Wheatstone IP-64 or WheatNet-IP Audioarts), the integration is seamless and the total cost of ownership can be lower because routing and control are unified.

Use Cases and Applications

Live Sound and Performance

Dante dominates the live sound market. Its low latency, automatic discovery, and widespread adoption by PA rig manufacturers make it the default choice for touring sound, festivals, and houses of worship. The ability to daisy-chain multiple devices and use redundant networks (primary/secondary) ensures reliability. Ravenna is less common in live sound due to higher setup complexity and fewer portable devices. WheatNet-IP is rarely used in live sound outside of broadcast truck integration.

Broadcast and Production

WheatNet-IP is the traditional stronghold in radio broadcast. Wheatstone's deep integration with consoles and automation systems (e.g., Audion Labs, WideOrbit) makes it a favorite for on-air studios. Dante is also widely used in broadcast, especially for newsrooms, production trucks, and master control rooms where multi-vendor gear is common. Ravenna shines in large radio and TV networks that require thousands of channels across multiple sites; its open-standards approach allows mixing legacy AES67 gear with newer Ravenna equipment. Many large European broadcasters (e.g., SWR, BBC) have adopted Ravenna for their infrastructure.

Installation and Fixed Install

Dante is the top choice for installed sound in corporate AV, education, and performing arts venues due to its ease of installation and maintenance. Ravenna is often used in larger installations (stadiums, convention centers) where deterministic performance and scalability are critical. WheatNet-IP is primarily limited to broadcast facilities, though some large government or corporate audio systems use it if they already employ Wheatstone equipment.

Cost Considerations

Upfront costs vary by brand and network size, but a few generalizations hold. Dante-enabled devices often carry a licensing fee embedded in the product price, which can add a small premium (typically $30–$200 per device). Ravenna is royalty-free, so manufacturers may pass savings to buyers, but the cost of compatible switches and the need for higher network expertise can offset this. WheatNet-IP Blades and consoles represent a significant upfront investment, but the tight integration often reduces the need for additional processing gear and reduces configuration time. For long-term operational costs, Dante's widespread support means easier troubleshooting and broader engineer availability; Ravenna may require more specialized network engineers; WheatNet-IP benefits from Wheatstone's support network but locks you into one vendor for expansions.

Making the Right Choice for Your Facility

The decision ultimately depends on your specific operational priorities:

  • If simplicity, wide device support, and low latency are paramount: Dante is the clear winner. Its ecosystem is unmatched, and the learning curve is gentle. It is ideal for multi-brand environments, live sound, and smaller to mid-sized installations.
  • If you need an open, scalable, and standards-based solution for a large facility with mixed vendor gear: Ravenna offers the greatest flexibility and future-proofing. It is especially appropriate for large broadcast plants and complex AV installations where deterministic performance over many hops is required.
  • If you are building a new broadcast facility or upgrading an existing Wheatstone infrastructure: WheatNet-IP provides the deepest integration with Wheatstone consoles and processing. Its unified control surface reduces operator training and can streamline workflows in a single-vendor environment.

Many facilities eventually operate more than one AoIP protocol — using Dante for studio-to-studio transport, Ravenna for backbone distribution, or bridging via AES67. Understanding each system's strengths and limitations will help you design a network that meets both current and future demands. Evaluate your infrastructure, consult with system integrators experienced in these platforms, and conduct a proof-of-concept test with your most critical audio paths before committing to a single standard.
