Hi,
Just wondered if it would make sense to wire a xlr cable to stereo line
in of a computer by connecting the hot and cold rails to left and right
channels and decode this balanced signal to mono signal in software.
Would that make sense? Has anyone already done simple jack app that
would make this or should I have a try on this?

Hi -
I've done that in the past (not by choice though!). In SuperCollider
this would decode it and play it out:
x = { In.ar(0) - In.ar(1) }.play;

Yep, thats what I figured. Was just wondering that if there is ome
magical reason why it would be bad thing to do after louzy mic/line
input of a soundcard. What would make it even worse decision than to
just use the unbalanced cable.
I'm hoping to have this one simple app that isn't doing anything else
than this conversion and what I could route the input signal through in
jack. So something like command line app with no parameters. Just start
it and route the channels in jack. Would be very simple to do, although
a source code of super simple jack app would be usefull as I have never
programmed a true jack app, only couple using fluidsynth as a soundengine.

i think the noise of the preamp da-converter will sum up so that this is
only a emergency solution.
you can generate a command line app with faust.
i think you can put the following code into the online compiler

Yep, I'm building a live setup and in a way am more afraid of the hums
from stage lights and such than noise from soundcard input.

Thanks! I have never heard about this Faust thing and it actually works.
Sweet.
