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.
jack_export --chan 16 my16channelfile.wav
Jack_export will connect to the 'export' bus if it exists, and print
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
When the export terminates, jack_export will print a completion message
reporting the number of seconds recorded.
