This lovely open-source sound recording and editing program runs on Windows 2000, XP, Vista, 7 and 8, and is also available for other platforms, though the protocol for recording sound output is probably different on different operating systems. A feature was recently added that lets you choose a sound output device as an input device – so for instance, you can choose your speakers as your microphone

This is a tricky question I’ve bumped up against multiple times. What if I want to record my computer’s sound output? I can use the microphone to record what’s coming out of the speakers…but there’s naturally going to be a large loss of quality, since the sound has to go through both my bad speakers and my bad microphone. It would be much better to to have software on my computer directly record what’s coming out of my computer. If you do a little searching, you’ll find lots of people saying, “Oh, just use Audacity and select ‘Stereo Mix’ or something of the sort as the microphone!” Sorry…but not all computers support that – including mine! You will probably also find various programs that promise to record sound output…but that you have to, like, pay for. Which perhaps is fine if you intend to be recording sound output a lot, but not for me, who only needs to once in a while. But despair not! There is a free solution
