jack_capture is a program for recording soundfiles with jack. It's default
operation is to capture whatever sound is going out to your speakers into
a file, but it can do a number of other operations as well.

Note that the above link doesn't seem to currently work
because of something which seems to be www upgrade
at Notam. But this link does seem to work for now:


0.9.10 -> 0.9.17:
  *Made sure the process thread won't continue sending
   data when jack_capture is told to quit. This
   led to a race conditions when recording too many channels
   at once (which was 256 channels on my machine).
  *Added the jack_capture_gui script, based on code
   by Svend-Erik Kjær Madsen's.
  *Replaced sh by bash to make it work in ubuntu.
  *Fixed exact port name match and gen_setformat. Thanks to
   Gabriel J.L. Beckers for reporting the bugs.
  *Increased the time the console meter is displayed in red from
   50ms to 2000ms. (when the recorded jack value is equal to or
   higher than 1.0.)
  *Added the -dBr argument to specify reference level when using
   the console dB meter.
  *Added the -mr argument to specify reference level when using
   the meterbridge meter.
  *Added peak indicators to the console meter. Code to do so taken
   from meterbridge by Steve Harris.
  *Updated --help and README with the new options.
  *Added option "-mt" to change meterbridge type. Current valid
   options are vu (default), ppm, dpm, jf or sco. It's not necesarry
   to specify "-mb" if using "-mt".
  *Added option "-dB" to get a dB meter for the console meter.
  *Added examples how to record ogg and mp3 files using the -ws option.
  *Decreased default buffersize from 60 to 20 seconds.
   (I even had trouble provocing underruns using a minimal
    0.05 seconds long buffer, so 60 seconds was obviously overkill)
  *Fixed message and error printing to stderr when
   vu meter is running.
