[pulseaudio-discuss] What's the easiest way to capture audio that is being played over the PC's speakers?

I'm trying to figure out the easiest way to capture the audio that my Ubuntu Linux PC is
playing and save it to a file.  I don't want to capture from a URL.  I also don't want
to capture through the microphone, or analog capture device.  I simply want to
capture the bits that are being sent to the sound card.  My system uses pulseaudio.

I can currently capture the sound with a GUI program called audacity. I'd like
to do it with a command-line program instead.  I think avconv or arecord can
do this, but I've tried dozens of examples and can not get it to work.  I think
this should be a FAQ, but I can't find anything on the WWW that works.  Can
someone help out?  Thanks.
