Audio networking system
But, audio networking has one very large difference. Once that connection is made, those two devices will speak to each other only. If you want to connect more than two devices, you need one of the devices to have multiple ports, each with its own cable etc, etc.. The issue here is that those connections are static and the only way to change them is to start unplugging and re-plugging devices. AoIP, rather than forcing static interconnections between devices, allows the user instead to use a standard, off-the shelf, network switch to become a type of router that allows all the devices to talk to one another. Hundreds of channels of real-time audio can be transported using AoIP protocols, at incredibly low latencies, to be sent to and from any of the devices on the network.

Cybersecurity Awareness Month
An entire facility can be wired in hours, instead of weeks. But at the same time, it's a natural continuation of general trends and what you already know. Here, the microphones, speakers, and codecs are interconnected using AES67 instead of Livewire. Every source has a text name and numeric ID. These are transmitted from source devices to the network. Devices that play audio build lists of all available sources from which users can select.
Using Telos Alliance xNode audio interfaces, you enter the names of your input sources via any PC with a web browser. Livestreams have small, frequent packets optimized for live audio that requires very low circa1 ms.
Standard Streams are also real-time streams, but with bigger packets, and are used for audio streams which don't require super-low latency—like audio from CD players, or that exchanged with automation system PCs.
Devices that connect to Axia networks can transmit and receive both stream types; the user selects which type to generate when a device is initially configured.
An Ethernet system with a switch at the center may have a mix of audio nodes and normal servers, PCs, etc. Even on a single link, traffic can be mixed because we use modern Ethernet's priority mechanism to be sure audio packets have first call on the link's bandwidth.
A studio audio delivery system can use this capability to download an audio file from a server, for example, while simultaneously playing another audio file live. Telos Alliance digital xNode audio adapters deliver dB of dynamic range, with less than 0.
Since the very beginning, the Telos Alliance has based its AoIP networking technologies on standards. As charter members of the AES X. Impressive, no? But there are even more exciting things in the future.
We were charter, supporting member of the X. Here are some resources to help answer your questions about the history and specifics of Livewire, AES67, and more.
Learn about the features and technology behind xNodes - the first audio interface to support a connection protocol besides our own. What's the Deal with AES67? First, we promoted interoperability using the standard IP networking technologies built into Livewire, beginning in Then we became sustaining members of the X.
As part of the X. During this process, we made available, at no charge, parts of our own patented technology to help speed development of the standard. Compliant means that it fully complies with all parts of the AES67 standard. The difference is subtle, but important — compliant is not the same as compatible! For the purposes of the standard, high-performance audio refers to audio with full bandwidth and low noise. These requirements imply linear PCM coding with a sampling frequency of 44,1 kHz and higher and resolution of 16 bits and higher.
High performance also implies a low-latency capability compatible with live sound applications. The standard considers latency performance of 10 milliseconds or less.
This standard provides comprehensive interoperability recommendations in the areas of synchronization, media clock identification, network transport, encoding and streaming, session description and connection management. When we developed Livewire back in the early s, we had to synthesize the critical links between networking technologies, because a full standard didn't exist yet — and earlier networked audio systems lacked critical functionality.
We also recruited partner companies whose products are respected and widely used in the radio industry. Then we shared our technology with them, so that station engineers could connect as many audio devices as possible directly to their audio network. The goal is for every studio audio device to eventually click together with CAT-5 and share audio. Why is AES67 even needed? One critical piece of tech was network clock sync. Problem was, the Ethernet standard in place at the time had no criteria for high-precision time-synched audio.
Why is this so critical? So we invented the first distributed high-precision clocking system for Ethernet, and debuted it in Livewire. Although we have always been happy to share our tech with software and hardware manufacturers, other, open methods of Ethernet clock sync emerged, one of which became the IEEE synchronization standard — which is an integral part of AES Implementing a new standard always takes time, as manufacturers adapt existing products, design new ones, and release software updates.
The whole idea of AES67 is to open up more equipment choices when you buy. However, the AES67 specification provides interoperability standards for audio only — not for control or data exchange. Nor does AES67 equipment have the ability to automatically discover available audio, and present it to the operator for use. Most engineers agree that these abilities are a big part of the AoIP advantage. Contact Us About Livewire Partnership.

DANTE AUDIO NETWORKING - An overview
This idea misses the mark. Instead, audio networking also known as Audio over IP, or AoIP is a combination of software, hardware and network protocols used to deliver uncompressed, multi-channel and low-latency digital audio over a standard Ethernet network. AoIP transports audio between devices in real time by using standard IP technology and it has a variety of advantages and benefits relative to the older, analog method of connecting devices. Audio networks, therefore, are essentially the same as the computer networks we use every day for email , file transfers and more, and the two are compatible with each other.

AES: Network Audio Systems
There has been a concerted call towards going digital in pro sound applications and the real-world applications of this brand of networked sound have shown up in places as diverse the G8 Summit for sound reinforcement, the Sydney Opera House and recording applications at a member church in Vancouver, Washington. Digital audio networking systems offer plug-and-play operability by putting digital audio onto a local area network. While this development that merges audio with IT has a lot of potential benefits, it also comes with its own unique set of challenges and costs. For decades now, computer networks have been used to connect multiple computers and other digital equipment. It is a cheap and efficient way for devices to share data and for users to communicate and share the same piece of equipment, such as a printer or a storage device.
(Not So) Basic Networking For Live Sound Engineers
Read Part One Here. Now that we have laid the groundwork for a foundational knowledge and vocabulary of networking, we can move into how we put this together to construct a network for practical applications in the world of live sound. The last blog talked about basic structures of point-to-point transmission and ended with incorporating switches and routers to build another level of complexity to our signal flow. In this blog, we are going to put on our network system designer hats as well as our engineering hats to think about what we are trying to accomplish with a network in order to determine how we should build it, how we should divide it, and what level of redundancy we wish to build into our design.
Dante is a combination of software, hardware, and network protocols that delivers uncompressed , multi-channel, low-latency digital audio over a standard Ethernet network using Layer 3 IP packets. Like most other audio over Ethernet technologies, Dante is primarily for professional, commercial applications. Most often, it is used in applications where a large number of audio channels must be transmitted over relatively long distances or to multiple locations. Digital audio provides several advantages over traditional analog audio distribution. Audio transmitted over analog cables can be adversely affected by signal degradation due to electromagnetic interference , high-frequency attenuation , and voltage drop over long cable runs.
Audio networking as easy as. Whatever scale and flavor of audio networking the system demands, Soundweb London and DriveCore Install Series together provide the solution. It is now possible to move from one networked audio transport to another and stay on the same control platform without needing to learn multiple software applications. A is for. AVB ensures high quality audio and video streaming over Ethernet. What sets AVB apart from other Ethernet audio transports is that the network switches themselves ensure that media data is given complete priority over any other data on the network. Audio is guaranteed to arrive at the destination device with no interruption even possible.
The following is a comparison of audio over Ethernet and audio over IP audio network protocols and systems. From Wikipedia, the free encyclopedia. AES50 and HyperMAC are point-to-point audio connections, but they bridge a limited bandwidth of regular Ethernet for the purpose of control communications. The system topology may therefore follow any valid Ethernet topology, but the audio routers need a priori knowledge of the topology.
