For nearly two decades, networked audio research using jacktrip has shown that multi-channel uncompressed audio was possible over a National Research and Education Network (NREN) and was now becoming viable over some public network connections. There was however, a ‘Dirty Secret’, in the absence of any synchronisation between transmitting and receiving word clocks, periodic audio loss due to data over-run or over-run was a certainty. The authors describe a low-cost GPS-derived clocking solution for jacktrip and then apply it to off-the-shelf Dante equipment and Dante Domain Manager for the world’s first long-distance Dante audio over standard academic networks.
