New subject: Physical distance performance with Linux?
The one thing I remember about soundjack from the presentation at
tonmeistertage years ago was that inter-continental latencies are MUCH
worse than in-country, often to the point of not being very usable. This
isn't due to soundjack but the nature of routing across sub-ocean links
etc. Just something to be aware of if you're trying to connect and work
with people a *long* way away.

Hi,
we were just playing remote a few minutes ago. We used soundjack with a
round trip time of 50ms and less, since we all live in cologne but our ISPs
peer in Frankfurt. Thus, you should be able to achieve such latencies from
everywhere inside germany. But I don't know about other countries.
We are playing some hard rock stuff with tempo of 120 bpm and more. If you
try to be in sync with each other, your tempo goes down. If you want to
maintain the original tempo, everybody has to maintain their own tempo and
play a litte before the time you hear your mates. Then everybody can hear
their remote team mates in sync, only you yourself are too early.
After some practice you get used to this...
Best,
Ck

In our current world situation I see a lot of
videos, and in some cases
live, performances by multiple musicians/vocalists in physically
different locations.
Some are obviously in a MacGyver setup in the closet, others are in
rather tricked out home studios (like the one I just watched of the
Doobie Brothers, where they all were in their own studio).
Some are obvious compilations, video effects, etc. added. But, when
they
are live how do they deal with delays and
monitoring for the local
performance (in the Doobie's one, there was some post processing, but,
the duets seemed really tight, both instruments and vocals.)
My question is, have any Linux folks had any experience setting this,
with Linux tools obviously..., and how did you deal with delays and
monitoring when live or (I assume when processed video is involved)
monitoring and delay for multi-tracking from around the world?
There are several tools out, some of them open source based:
jacktrip ( https://ccrma.stanford.edu/software/jacktrip/)
soundjack ( https://soundjack.eu/, closed source)
jamulus ( http://llcon.sourceforge.net/)
Just to name a few.
We developed our own system based on zita-njbridge and some self-written
network managing tools, which we use almost every day:
https://github.com/gisogrimm/ovbox
The delay which can be achieved (with all of the systems - the
underlying network is the most critical factor) will be in the order of
30-80 ms between musicians (one way). 30-50 ms feels more or less ok, if
it is more you need to play actively before the time.
Best,
Giso

Mac

That should also apply in general to the number of routing devices the
link has to traverse, and general distance. So same city would be better,
same ISP in the same city wold probably be better still. Best would be
same building connecting through a single building Ethernet switch.
I watched that Doobie Brothers performance originally mentioned, and I
don't think that was live. That is one possibility if you don't mind,
have one person start a session then pass it around, everyone adds their
part. Not as enjoyable as performing together with other people, but
probably results in a better quality performance overall.

in our setup we are five participants, all in North Germany (Hamburg,
Bremen, Oldenburg and two villages not very far away). Interestingly the
peer-to-peer ping times are not much shorter than the added ping times
from the peers to the server (in Frankfurt) and back to the other peers.
