Today, Artel Video Systems announced that it has extended its suite of Quarra PTP Ethernet solutions to the professional audio market — a market that eventually must migrate to IP-based workflows just as other media markets are doing. For adopters of audio-over-IP in pro audio (aka: Dante), Quarra switches are PTP-aware.

So far, the use cases for Quarra have fallen under the early-adoption category, where the technology is being used primarily to solve timing and synchronization problems in pro audio kits. For example, Recording Engineer and Founder of FiLO Classical, Dave Rowel, uses Quarra PTP-aware switches to stabilize traffic clocking and reduce drift to about 15 to 45 nanoseconds, which is well within the range of his RAVENNA-based real-time audio-over-IP system. Overall, Quarra helps him manage several bidirectional connections over varying distances and cable lengths, especially at gigs with 60-plus channels running at a typical speed of 192kHz.
