I've had very little use for netjack, so I'm not very familiar with it's
limitations, but I can only assume it was not sufficient for your use case. So
out of curiosity, what was the motivation behind creating this?
There are a number of differences. I can't tell for sure as I have a newer
computer since I was playing with netjack ;) but njbridge seems to use
less CPU, It is easy to set up, seems to affect jack less (on both ends)
because it is a client and not internal like the -net backend for jack.
njbridge can work with any jack on any end: it does not matter which one
is master, but there could be three computers with jackdbus, jackd2 and
jackd1 all bridged. There is no limitation of audio interface on only one
(master) server. There is no requirement for all servers to be phyically
synced. With netjack, both ends not only had to be the same jack (jack1 or
2) they also had to be the same version. (I had more differences in my
mind but lost them while typing)
The link can be lost without killing one end's jack server... or even the
connections within jack. Multi-casting is possible, one server can send 5
outputs that one server can collect channel 1and2 while the next has 3and4
while another takes 5 only... and maybe another grabs 12and5 and another
grabs 34and5. (think two stereo mixes and a tally line) none of them needs
to process the channels they don't use.
Think of a radio station with three studios (CBC in Frobisher Bay in 1979
or so but analog everything) each studio has its own audio interface and
computer with a jackserver. In many ways they are separate and work on
there own, one of them being the on air control and the others for making
commercials or prerecording shows. But sometimes it is also needed to send
audio from one studio to the next. Jack does not have to be stopped, just
njbridge started... and ports connected... the on air control may have
njbridge running all the time... maybe even two of them that the other
studios just connect to when needed.
This does not make netjack outmoded, netjack has it's own uses where two
fully synced machines are used. This just opens up a lot of new uses or
works better for some uses than netjack could.
