AES50 only supports 100Mb/s Ethernet, and without the protocol header requirement, this essentially makes it a clear, 12.5MB/s bi-directional channel, on which (almost) raw sample data is transmitted. Rather than thinking in terms of an audio interface connected to a host computer, we can think instead of an interface and a computer co-existing on a network, and internalise the fact that this model is eminently scaleable. Today, anyone wishing to add a high-quality, low-latency, multi-channel audio interface to a computer is spoiled for choice, with devices available in a whole host of formats: PCI, PCI Express, Cardbus, Expresscard, FireWire 400 and 800, USB Full-Speed, High-Speed and Super-Speed and Thunderbolt 1 and 2. Traffic arriving on any port can be forwarded to any other port’s — or ports’ — output queue(s) based on the destination address in the packet header. This website uses cookies to improve your experience. In production volumes, these solutions are supplied as bare ICs, giving the OEMs themselves the task of implementing the kind of support circuitry which the Brooklyn II module provides as standard, and otherwise dealing with the lower-level details of integrating Dante into their circuit designs. The second is a ‘correctionField’. The virtual soundcard can manage up to 64 channels at normal sample rates (or 32 and 16 at double and quad rates), though performance is ultimately host-dependent. This is exactly what AVB and Dante both do, but by somewhat different means. One way of addressing this problem is to classify certain types of traffic, and provide a separate high-priority queue for traffic of that class. PENTA 721s is a new generation audio router and audio distribution interface from NTP Technology, which provides a versatile and flexible interface for signal distribution of analog, and digital audio via AES/EBU and MADI, as well as routing via IP Gigabit Ethernet … Figure 2: A bridged network with half-duplex links. It specialises in audio interfacing over networks and is used in multiroom recording studios, mastering … A routed AES50 system is logically an ‘either/or’ switching matrix rather than an ‘anything-anywhere-anytime’ network. It wasn’t the first system of its type on the market — that accolade goes to Telos/Axia’s Livewire, introduced in 2003 — or even the second (Wheatnet IP arrived in 2005), and other players have subsequently entered the market, but none have had the impact of Dante. A Sweetwater Sales Engineer will get back to you shortly. In other words, any device can stream to any other device, but only if a third device isn’t already doing so. The larger the network, and the heavier the traffic, the higher the average latency and degree of uncertainty. As if to illustrate the principle that success breeds success, the increasing attractiveness of Ethernet at this time led many sectors that had previously relied on specialised networking solutions to begin investigating its possibilities, and ultimately, to become involved in its development. $1,689. Audinate recommend using three queues (four queues are typically available on a managed Ethernet switch of the type required by Dante), with PTP event messages using the highest priority queue, audio and PTP general messages using the second highest, and best effort (unclassified) traffic using the lowest. At 44.1kHz, for example, the required result is produced by alternating packets containing five samples with packets containing six samples, but substituting every 79th packet with a packet of six samples. For the uninitiated, networked audio and Audio over Ethernet (AoE) can seem inscrutable, a jargon-laden area reserved for only the most advanced pro audio practitioners. Developed in 2006 by a Sydney-based company named Audinate, Dante builds on previous audio over Ethernet and audio over IP technologies.. Like most other audio over Ethernet … The first is that any innacuracies in clocking have to be compensated for with additional buffering, which increases latency. The fact that a node doesn’t detect a carrier doesn’t mean that another node has not begun transmitting, merely that said transmission has not reached the first node yet. Some ethernet audio interfaces function on proprietary platforms, such as Wave’s SoundGrid devices and Behringer’s ULTRANET devices. Elsewhere, however, events were moving apace. 32-in/34-out Hybrid Thunderbolt/USB 2.0/iOS Audio Interface with 4 Mic Pres, 2 DI, 8 x 12 Line-level I/O, ADAT and S/PDIF Digital I/O, AVB Ethernet - Compatibility, and 48-channel DSP Mixer Onboard with … RedNet interfaces offer a selection of dedicated audio-over-IP interfaces including MADI, AES3, analogue, remote mic pres, and include options for redundant power supplies and network connections. Now each and every node and switch port in the network had its own dedicated, contention-free transmission and reception channels (Figure 3). Ethernet Audio Interface and DiGiGrid IOS Extension 24-bit / 192 kHz. In the former case, packets are not sent until six samples (at 44.1kHz) become available (approximately every 136.05µs), which simply means sending 7350 packets per second rather than 8000. From the perspective of applications, they appear as standard audio devices. By now the scope of the endeavour had expanded too, with the growing involvement of companies from fields such as pro audio, broadcasting and commercial sound among others. The Tascam US-16×08 is an 8 channel audio interface, aimed at being an affordable option for those wanting a rack-mountable audio interface with a decent amount of inputs/outputs. Universal Audio Apollo x8 Heritage Edition 18 x 24 Thunderbolt 3 Audio Interface with UAD DSP 18-in/24-out, 24-bit/192kHz, Thunderbolt 3 Audio Interface with 6-core HEXA Core Processor, Elite … Ethernet Audio Interfaces. With this in mind, the AES developed a standard called AES67 to facilitate just that. Behringer WING 48-channel Digital Mixer 48-stereo-channel Digital Mixer with 48-in/48-out USB Audio Interface, 24 Motorized Faders, 8 MIDAS Pro Preamps, 28 Stereo Buses, 16 Stereo Digital FX Processors, 64-track Dual-SD Recorder/Player, Ethernet … As bridging was where the critical work needed to be done, the project therefore moved from the 802.3 (Ethernet) Working Group to the 802.1 Working Group. The sum of the preciseOriginTimestamp and the correction field gives the synchronised time at node B corresponding to the time Ts1. Incidentally, if the involvement of a guitar company seems somewhat incongruous here, it should be noted that Gibson had by this time already developed an audio transport called MaGIC, which used the Ethernet physical layer, and indeed hoped that it would form the basis of the IEEE standard. Ethernet audio interfaces have some distinct advantages over USB or Thunderbolt interfaces. After these overheads, the 12.5MB/s data rate is good for 48 (fixed) channels in each direction at 48kHz, or half that at 96kHz; these are the only sample rates supported by AES50, which is aimed squarely at pro audio applications. Among them were parts of the scientific instrumentation community, and companies in the industrial automation sector. Audinate’s Brooklyn II provides a complete Dante audio interface on a card. Proprietary ‘matrix routers’ are available, but the name itself gives the game away: You can send anything anywhere, but not at any time. A world that increasingly relies on Ethernet won’t tolerate it getting broken just because some damned fool wants to play a guitar through it, so to speak. 1468/24 is 61.66, but since you can’t have a fraction of a sample, we can say that 61 channels is the absolute theoretical maximum for a single AVTP stream, independent of network speed. 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. The Class A observation interval is 125µs, while Class B’s is 250µs. This may seem like an extremely long time, but then like most standards bodies, the IEEE is an extremely cautious organisation, and that’s undoubtedly as it should be. The job of an audio transport protocol is to group samples into packets, and to add the information necessary to reassemble them at their destination while preserving their relative timing. So far we’ve been following Ethernet terminology and talking about a ‘shared medium’, but there’s another, more generic term which describes a communication channel which behaves in this way, and that’s ‘half-duplex’. The cable from your audio interface box can be anything up to 100 metres (328 feet) long, and every switch adds another hundred. Upon detecting the jamming signal, each node will ‘back off’ for a random period before making any further attempt to transmit. MOTU are among the manufacturers of project-studio equipment who have committed to the AVB protocol. If not, it isn’t a network.) As a result, that queue will contain packets of various sizes representing various transactions, all interspersed. The issue is that on entering a switch, all packets bound for the same onward link (to the next switch, for example), regardless of source or ultimate destination, go into the same output queue on a first come, first served basis. The Digigrid system from Waves and Digico is a ‘layer 2’ system, meaning that although it can use standard Ethernet hardware such as switches, it requires its own dedicated network infrastructure.Each Ethernet frame carries one sample per channel, interleaved on a per-channel basis, so the packet transmission rate is equal to the sample rate. Audio Video Bridging (AVB) is a common name for the set of technical standards which provide improved synchronization, low-latency, and reliability for switched Ethernet networks. In 2001, French company Digigram brought to market a rival system called EtherSound. They’re asking if it could empower their creative process — the short answer is yes. The new company took the name Audinate, and the technology they’d developed was christened Dante. 5501 U.S. Hwy 30 W, Fort Wayne, IN 46818 In an example of a phenomenon to which the recording industry perhaps owes its entire existence — developments in one field bringing incidental benefits to another — PTP unintentionally gave a massive boost to the possibility of making standards-based Ethernet a viable medium for high-performance audio and video transport; and, in the early years of the 21st Century, some major players began to take a serious interest in doing just that.

Almost as an added bonus, the bandwidth of each link was effectively doubled — since the rated transfer rate now became bi-directional — and medium-access latency was reduced to almost nothing. Moreover, several of the ethernet audio interfaces available from Sweetwater have their own onboard DSP for even more real-time processing power. AVDECC is an extremely comprehensive Layer 2 protocol which provides extensive mechanisms for device configuration, stream routing, parameter control, diagnostics, security and a host of other features. Each frame has space for one sample per audio channel (of which there can be up to 64 at standard sampling rates), hence the frame rate is equivalent to the audio sample rate, and acts as the clock source for the network. In America, Skylab is launched, and Richard Nixon confesses to his role in the Watergate cover-up. Luckily, product development kits (PDKs) are available for all three solutions, which provide both the hardware and software components of a complete reference design, along with the programming tools and documentation required to work with them. According to the character of Joseph Garcin in Sartre’s No Exit, “hell is other people.” Had Garcin been developing a high-performance audio network, he might instead have come to the conclusion that hell is other traffic. A YouTube video review of the Focusrite RedNet 2 by SOS contributor and Forum regular Robin Vincent, of Molten Music Technology, includes a comparison of its performance when connected to a PC via the PCIe card and by means of Dante VSC. Ethernet is a powerful multi-channel interface that sits at the super high end. Q. Phone Hours | The packet rate is simply a function of the class interval, and the sole purpose of the class interval is to limit stream bandwidth to no more than that commensurate with the maximum permitted size of a standard VLAN-tagged Ethernet frame, which at 1542 bytes takes 123.36µs to transmit on a 100Mb/s link (the minimum supported by AVB). Audinate have created an attractive ecosystem for audio manufacturers interested in adding networking capabilities to their products, offering a comprehensive set of hardware and software components which make integrating Dante into an audio device design a fairly straightforward process. These systems fall into two basic categories, usually characterised as ‘layer 1’ and ‘layer 2’ systems; however, these designations are somewhat misleading, because they imply a more fundamental distinction than really exists. The principal markets for CobraNet and EtherSound were large installations: conference centres, sporting venues, transport terminals, theme parks, and anywhere else where audio needed to be widely distributed. Before synchronisation occurs, each node measures the delay between itself and the adjacent node (or nodes, in the case of a switch) using the peer delay mechanism. The switch to full-duplex links finally eradicated the possibility of collisions on a shared medium network — by dispensing with the shared medium! An interface and a computer can easily become 10 interfaces and a computer for recording an orchestra, or 10 computers and an interface running a massive plug-in farm, and adding anything from a power amp to a mixing desk is just a matter of plugging it into a network switch. A more accurate categorisation might be: Those that include MAC headers (but don’t really use them, at least not in the conventional sense) and those that don’t. Choose Your Audio Interface In Your Operating System. The PCIe card and the VSC both provide ASIO and WDM support under Windows, and Core Audio support in Mac OS X, making them compatible with all modern DAW applications (not to mention the vast majority of audio software generally). Great care has been taken to ensure accuracy in the preparation of this article but neither Sound On Sound Limited nor the publishers can be held responsible for its contents. Yet, in principle, Ethernet has unique advantages over other formats, and it has already come to dominate the worlds of installation and high-end live sound. When any node in the process of transmitting data detects a collision, it stops transmitting that data and instead sends a predefined jamming signal. Perhaps even more significant is the fact that the standards-making process is a highly democratic one, to which each of the participants frequently bring different — and often contradictory — wish-lists for a given standard, all of which have to be haggled over, formalised, drafted, voted upon, reviewed etc. Because AVB streams are always associated with a stream reservation, any packets entering the AVB domain with the same PCP values as either of the AVB traffic classes automatically have their priorities reduced to a value below that of the AVB classes, and thus don’t find their way into the AVB queues. These caveats notwithstanding, the low-latency performance of the Dante PCIe card appears to be in a similar league to that of ‘gold standard’ interfaces from the likes of RME, Lynx and MOTU. Every 750 s, the conductor transmits a beat packet which is received by all of the performers. MOTU are among the manufacturers of project-studio equipment who have committed to the AVB protocol.AVB defines two traffic classes: Class A and Class B. It’s perhaps interesting, though, that said list already includes one potential exception to this rule, namely Thunderbolt, which appears still to be thriving in the sixth year of its commercial existence. The difference between the two intervals is the difference in frequency between the two clocks. Cookies help us improve performance, enhance user experience and deliver our services. Given its ‘lowest common denominator’ approach, AES67 is seldom used within a particular network, but rather provides a way for them to work together. 25 x 34 Pro Tools AVB Audio Interface with 8 Mic/Line Preamps, 8 Analog Line I/O, 16 Channels Digital I/O, Word Clock I/O, HDX DSP Plug-in Acceleration, and Software Package -

The unit of transmission in an AVB domain is the stream. Probably the first guitar to feature a built-in RJ45 socket, Gibson’s HD.6X was designed to take advantage of their MaGIC data-transfer protocol. Show. €1,429.31. The ASIO driver can freely access any input or output, on any audio interface (or mixer, or preamp), from any manufacturer, in any combination, as long as they’re all using the same AoE/AoIP protocol and are plugged in to a switch. Exclusive deals, delivered straight to your inbox. The Follow_Up message contains three pieces of information. While manufacturer’s including Focusrite, MOTU, RME, and Apogee utilize common audio networking platforms such as Dante and AVB. MOTU is a primary supporter of AVB and offers a wide variety of AVB-compatible products aimed at systems from single-user home/project studios with audio interfaces… 6 x Line output 6.3 mm jack balanced. Both CobraNet and EtherSound had high price tags, and the former in particular had a reputation for being difficult to configure. Obviously, no stream can exceed the available bandwidth of the link, which by default is limited to 75 percent of the total capacity, meaning 75Mb/s for 100BASE-TX and 750Mb/s for 1000BASE-T. Another limiting factor for a single stream has already been mentioned, and that’s the maximum allowable size of an Ethernet frame, which is 1542 bytes, with a payload of 1500 bytes. A bridge does this by storing (buffering) data coming in, then forwarding it to the next physical link, in essence creating two isolated collision domains where there used to be one. Samples may be inserted into or extracted from the packet as it passes downstream through each device in the chain. Following this paradigm, Audinate supply hardware implementations of Dante under licence to OEMs, who integrate them into their PCB (printed circuit board) designs. In 2009, a year after the first Dante-enabled product (the Dolby Lake processor) hit the market, the first of a set of IEEE standards which collectively define AVB was published. However, there are a couple of potential problems with a simple priority scheme like this. AES67 specifies a subset of protocols common to all of the above systems (or easily implementable if not) which allows bridging between one AoIP technology and another. The participation of these parties led to the publication in 2002 of IEEE Std 1588. While thousands of CobraNet and EtherSound networks are still in use worldwide, you may have noticed that the previous paragraph discussed them in the past tense. The difference in frequency between the GM and the local clock at node A is known as ‘rateRatio’. The first commercially viable audio-over-Ethernet systems were CobraNet (above) and EtherSound, as implemented here in expansion cards for Tascam and Yamaha digital mixers.The first of these Audio over Ethernet (AoE) systems, as they came to be known, was CobraNet, developed in the mid ’90s by a small Colorado company called Peak Audio, and later acquired by chip makers Cirrus Logic. Finally, we come to Thunderbolt, which on the face of it holds the most promise for audio … Add to Wishlist Add to Compare. This involves an exchange of timestamped messages as shown below. It goes without saying that the rapid pace of technological advance would never have been maintained if Ethernet had not simultaneously been enjoying massive commercial success. In addition to the Ethernet physical layer framing, AES50 interleaves a small amount of error-correction metadata too, and also reserves a 0.625MB/s Ethernet/IP channel for out-of-band communication. Ultimately, development goes hand in hand with investment, and investment follows the bottom line. So while carrier sensing reduces the likelihood of collisions, it doesn’t eliminate them, and this is where the second part of the protocol comes in. Where Audinate differ from competing developers is partly in the markets they target, but chiefly in their business model. Ethernet Audio Interfaces. Can I reduce latency when using Dante Via and Cubase? £1,239. Carrier sensing alone, however, provides only a statistical defence against collisions, the reason being that signals take time to propagate throughout the network. Class B is AVB satisfying both its RESG heritage, by accommodating consumer-friendly technologies, and its 802.1 mandate, by not being Ethernet-specific. Focusrite’s Dante-based RedNet system is the first Ethernet audio range targeted (in part) at the recording studio market.A little over a decade later, Dante is firmly established as the de facto standard for high-performance AoIP (Audio over Internet Protocol). In effect, the network is ‘reset’ as a means of quickly recovering from a collision. The idea behind IEEE 1733 is to allow the low-level AVB enhancements to be utilised by Layer 3 networks, and provision for this is made in AES67 (see the ‘LAN Mass’ box). All EtherSound devices have two network ports — In and Out — and are connected in a daisy-chain topology. Anyone wishing to explore the nuts and bolts of AVB may be interested to know that all 802 standards are downloadable free of charge via the IEEE Get Program (http://standards.ieee.org/about/get/#get802). Some observers have pointed out that no proprietary interface format has ever succeeded in the long term, and indeed, a glance at those listed in the opening paragraph of this article reveals the long-standing preference for standardised formats.
