Audio Network Technology
Today’s AV applications make use of networked audio as a means for audio distribution. With Dante® audio networking from Audinate, AV system designers now have an audio network that excels in five important objectives: fidelity, stability, flexibility, ease of implementation, and ease of use. Dante audio networking provides digital audio distribution over local and wide area networking, using standard network hardware or by connecting into a standard network infrastructure. This provides many advantages, including audio system scalability, easier installation, and simplified wiring. Dante allows uncompressed high resolution digital audio to be distributed across a switched Ethernet network using standard TCP/IP protocols, while meeting the stringent quality requirements of professional audio.
Enterprise network environments often require security and logical segmenting which can make the implementation of an AV over IP solution challenging. Similarly, it can be desirable to protect AV routing, and other settings, from being changed by unauthorized users. Dante Domain Manager (DDM) from Audinate is network management software that provides solutions to these challenges. DDM enables user authentication, role-based security, and seamless expansion of Dante systems over any network infrastructure.
The AES67 standard provides interoperability between the predominant Audio over IP protocols in use today. AES67 was developed by the Audio Engineering Society, published as an open standard. AES67 is an interoperability standard that acts as a translator between protocols. To take advantage of AES67 within a networked audio system, all system components must have implemented AES67 by itself or on top of their native protocols. Therefore, it is highly advisable to research what is implemented on the specific devices that will interconnect via IP within a design.
