But do you have anything to connect it to ?

A backend using the njbridge format makes sense only when 
connected to some hardware audio interface (analog or digital),
or to emulate netjack.

The latter means a master/slave relationship, which is exactly
what the whole njbridge design wants to avoid (two reasons for
that being that 1. it doesn't scale and 2. it's fragile (if the
master has a problem the slaves will fail as well).

What would make sense is an option in the njbridge receiver
that would make it assume (and check) that the sample clock
is synced to the one of the backend, and bypass resampling.
All the rest of the logic would stay in place, to ensure
a defined latency regardless of how the periods on backend
and transmitter are aligned (they could even be different).



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
