"Its default operation is to capture whatever sound is going out to your 
speakers into a file."

You don't have to think. If you have something cool going on in your 
loudspeakers and need to record something now, in a hurry, you 
remember that the recording program started with the name "jack", you 
write "jack" + tab tab in your terminal, one of the options is 
"jack_capture", select that one, and press return. Thats it, everything, 
such as connecting ports, selecting a unique non-cryptic filename, and 
selecting a well supported file format with best possible quality, is 
taken care of, and the recording starts immediately. You don't have to 
reconnect ports later either. If you reconnect your jack ports during 
recording, jack_capture automatically reconnects its ports as well, so 
that everything you hear, no matter how its connected before or after 
jack_capture starts recording, is recorded into the file.

jack_capture also buffers a lot so the chance of getting a disk underrun 
is extremely unlikely, and if you reach the 4gb barriere for wav files, 
jack_capture automatically continues to record in new file.

Jack_capture also has a lot of options, such as selecting channels, file 
format (try "jack_capture -f flac"), input ports to connect to, output 
ports to connect to, how long time to record, how many channels, filename. 
But normally you don't want to do that, just write "jack_capture" and 
thats it.
