is there a difference between this and
jack_capture --channels=16--port=ardour:export/out\*
my16channelfile.wav
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'.
jack_capture can already use the transport system to start and stop
recording,
so adding an option to record during freewheeling shouldn't be very
hard.
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.
jack_capture does that too, except dithering. jack_capture also uses
WAVEX as the default
format for > 2 channels.
Hmm, I might steel your freewheeling and dithering code into
jack_capture. :-)
