What is Dante Audio?
Dante (Digital Audio Network Through Ethernet) is a proprietary technology developed by Audinate that allows uncompressed, multi-channel digital audio to be transmitted over standard Ethernet networks with extremely low latency. Instead of relying on traditional analog cables or point-to-point digital connections, Dante uses standard IP networking, making audio routing more flexible and scalable.
Key Features
- Uncompressed, high-quality audio: Delivers pristine, professional-grade sound without degradation.
- Low latency: Typically less than 1 millisecond, suitable for live sound and broadcast applications.
- Channel capacity: Can handle hundreds of audio channels over a single network cable.
- Synchronization: Uses precise clocking for sample-accurate playback across all devices (no drift).
- Plug-and-play: Devices automatically discover each other on the network using Dante Controller software.
- Scalability: Works over standard switches and routers, allowing systems to grow from a few channels to thousands.
Typical Applications
- Live sound reinforcement (concerts, theaters, stadiums)
- Broadcast and recording studios
- Installed AV systems in corporate, education, and government spaces
- Houses of worship
- Anywhere multi-channel audio needs to be routed reliably and flexibly over IP
In short: Dante Audio replaces bulky analog and digital cabling with a single network cable, giving AV professionals a simple, scalable, and rock-solid way to manage audio across devices and locations.
