#DANTE VIRTUAL SOUNDCARD PROS AND CONS PORTABLE#
Fortunately many options exist from portable 5 port switches through to rack mount, high port count switches from major industry players such as Cisco, Extreme Networks, Luminex, Netgear, amongst others.įor the purpose of this article I physically separated my Dante network from the AVB network in order to get up and running quickly.
#DANTE VIRTUAL SOUNDCARD PROS AND CONS UPGRADE#
This requirement can sometimes be a stumbling block for some installations, in that you generally cannot simply upgrade an existing switch to support AVB, you have to replace the switch with one that supports AVB. There are a couple of requirements for AVB to work, the main one being that AVB compatible switch must be used. It is also worth bearing in mind that, unlike Dante, AVB is an open standard. However, even when running smaller channel counts there is certainly an advantage to a deterministic network, purely for peace of mind that a sudden spike in network traffic will not derail a recording session that is in progress. An AVB capable network reserves some bandwidth in order to guarantee that packets are delivered on time. The advantage with a deterministic networking model becomes more apparent when running very high channel counts that are approaching the total limit of the network. As such I’ve never had any issue running the maximum number of channels I have available to me on my converged network (that is running, data, video and audio on one network). You may be aware from my previous articles that I run a 64 channel Dante network which is moderately large in studio terms, but compared the to maximum number of channels possible it is relatively tiny. With AVB the precisely timed delivery of packets is part of the standard.
Dante instead uses a function called Quality of Service (QoS) to prioritise some packets over others. Looking at Audio over Ethernet more broadly, for most people using AoIP technology in the recording studio the advantages of either technology will afford high channel counts, 100m cable runs using relatively cheap ethernet cable, easy scalability and advanced routing capabilities.īy way of comparison, Dante works a little bit differently in that packet delivery is done on a “best effort” basis- there is no guarantee to the timely delivery of packets intrinsic in the technology. AVB In BriefĪVB is essentially an extension to the IEEE 802.1 ethernet standard and it is deterministic in nature, which means that packets are guaranteed to be delivered to their destinations on time. I’ve been interested in audio over ethernet technology for some time and have a fair amount of experience running my own Dante network but this is my first time using AVB products. I have been provided with a brace of three products that support the AVB (Audio Video Bridge) Audio over IP standard, namely the petite but powerful RME Digiface AVB audio interface as well as the RME AVB Tool audio converter and RME 12Mic mic preamp for this product review.
Audio Over IP products are becoming more common in the recording studio, with several competing formats available, namely AVB, Dante and RAVENNA.
