Jack_export is a simple command line app I've been using to do multichannel
exports from Ardour2 sessions. Of course A3 provides this OOTB, but I will
maintain jack_export to provide (if necessary) formats and options that A3
doesn't or won't support.
This release does not include resampling, the sample rate of the exported
file will be the current Jack sample rate.
To use, proceed as follows:
1. (Optional) In Ardour, create a bus (not a track) named 'export', and
containing all the signals you want to export. You can skip this step,
in that case you'll have to connect Ardour outputs to jack_export inputs
manually after step 2.
2. Run jack_export. See --help for options. The --chan option is mandatory.
E.g.
jack_export --chan 16 my16channelfile.wav
Jack_export will connect to the 'export' bus if it exists, and print
Ready ...
If you did not create an 'export' bus in Ardour, now connect Ardour
outputs to jack_export inputs manually.
3. Do a normal export in Ardour, using some dummy name for the exported
file. As soon as Jack goes into freewheeling mode, jack_export will
print
Recording ...
When the export terminates, jack_export will print a completion message
reporting the number of seconds recorded.

AFAIK, jack_capture records in real time. Jack_export records while
Ardour is in freewheeling mode during exporting, so it's usually
'faster than real time'.
Also, jack_export will ceate a proper WAVEX file (standard WAV must
not be used for > 2 channels) or CAF, or Ambisonic WAVEX, and provide
different output formats and optional dithering.

I'm still a bit confused. When I do a normal export in Ardour, I get
the mixed 'master' track as output. You're saying that jack_export will
produce a multitrack WAVEX file of the component tracks, not the mix on
the export bus?
If its recording the component tracks, are they raw, or after the
application of any plugins and gain automation?

Nope. jack_export does the right thing[TM] when your master-bus is more
then two channels. Like in ambisonics where it starts at four channels
and scales up in output channels well beyond the average band-setup
input configuration ;-)
Have fun,

If not, you can connect whatever you want to record manually, this can
be the outputs of individual track strips, sends, whatever, including
outputs from other Jack apps.
Recording starts when Jack enters freewheeling mode, and stops when
it returns to normal operation.

If you are doing a multichannel mix then you would normally
use the 'export' bus as the master output but you don't have
to. You could create it just to collect all the signals you
want to export.

Thanks! I'm starting to get the idea. That multichannel panner is pretty
cryptic, so I'm glad to bypass it and just use the bus channels 1:1.
