Madi can be sub-ms RT (return trip)
Really? Coax, optical or both? I used MADI routers in my work but that
was more about sharing multi-channel audio across sites miles apart than
low-latency monitoring... (I also have to sadly admit the MADI system is
one of the ones I new the least about by the time I left that job :( )
FOH snake use seems to require ~3ms RT
Sounds like CobraNet at it's lowest
latency setting (1.33ms per
direction, plus a little propagation delay.)
I assume people have heard and read up on AES67? I admit I haven't
beyond skimming it and can't say I'm sure whether it's its own
specification or more about getting the various existing solutions to
communicate together. Probably worth reading though...
