Re: [LAU] Sync and digital audio transport

Working my way through the AES3 variants (AES3, 10, 11, 47) and came across this page: http://www.glensound.co.uk/uat/pdf/atmaes47/atmaes47is.pdf It is about using AES47 as a method of sending AES3 streams over net. (simplified definition) Anyway this company make equipment for sending/receiving audio streams to/from remote sites. At the bottom there is this statement: ------------------8<----------------- Inevitably sites are not always locked together. To cope with this our AES47 equipment incorporates a clever algorithm that is capable of realising that two clocks are not locked together and then as necessary to prevent audible jitter the equipment will drop or repeat samples during periods of silence in the audio or if not available during periods of consistent similar frequency and level. ---------------8<-------------------- Is this method of sync common in the professional world? How does it compare to resampling when the frequencies are very close? -- Len Ovens www.OvenWerks.net
