Talking about Dante Digital Audio Transmission Technology
Dante digital audio transmission technology is a three-layer IP network technology that provides a low-delay, high-precision and low-cost solution for point-to-point audio connection [4][5]. Dante technology can transmit high-precision clock signals and professional audio signals over Ethernet (100M or 1000M) and perform complex routing. Compared with traditional audio transmission technology in the past, it inherits all the advantages of CobraNet and EtherSound, such as uncompressed digital audio signal, ensuring good sound quality effect; The complex wiring problem in traditional audio transmission is solved and the cost is reduced.

Compared with traditional audio transmission technology in the past, it inherits all the advantages of CobraNet and EtherSound, such as uncompressed digital audio signal, ensuring good sound quality effect; The complex wiring problem in traditional audio transmission is solved and the cost is reduced. the existing network, no special configuration; Audio signals in the network are marked in the form of "tags". At the same time, it has its own unique advantages:
1) smaller delays. At 100M network bandwidth, the latency is only 34 microns while the total transmission audio channels are three. Dante system can automatically adjust the available network bandwidth to minimize delay time.
2) IEEE1588 precision clock protocol is adopted for clock synchronization.
Zeroconf (Zero Configuration Networking)[6][7] protocol is adopted to automatically check interface devices, identify labels and distinguish IP addresses through the automatic Configuration server. It does not need to launch high-level DNS or DHCP services, and at the same time saves complex manual network Configuration.
4) high compatibility of network. Dante technology allows audio signals and control data and other unrelated data streams to be Shared in the same network without interference. Users can make full use of existing networks without setting up a private network for audio system. For example, Dante network can be used to add existing common TCP/IP devices (PC, etc.), or some audio processing software.
5) self-healing system. To avoid accidental interruption of audio transmission, Dante system can set multiple self-repair mechanisms, such as clock loss and network failure.
6) the transmission mode of audio channel can be unicast or multicast. Dante technology can be managed by IGMP(Internet Group Message Protocol), and the broadcast audio channel can be filtered or blocked according to the needs of the receiving point, which makes the routing of multicast audio controllable.
These unique advantages will be the cornerstone of Dante technology in professional audio and other engineering fields.
Dante audio transmission technology
There are many network technologies available in the IT industry, but Ethernet is still the most reliable and widely used protocol. Therefore, Audinate has also become a reasonable and marketable choice to run Dante on the Ethernet. Dante audio transmission technology allows audio signals to be transferred arbitrarily over Ethernet using TCP/IP and keeps the * restore of the signal in the process.
3.1 basic principle
Using MONISMS 'new products, digital audio transmission based on Dante technology can be realized. It truly realizes the function of "plug and play" of audio network, which is convenient for those who do not know any network technology.
