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 Kj=E6r 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.
