Audacity is a free music editing program and with the proper settings will record anything that plays on your sound card. There is still much I do not know about Audacity including how to set the record sound level but it is fairly simple and works well enough for me. Once I have a recording, I highlight the sound waves and click amplify from the "Effects" menu. On the bottom toolbar you will find four boxes that will offer options which can be selected. In the first box I have "MME". The second will be the sound card which Audacity might find on its own. It should be one of the selections you get when you click on the little arrow on the right side of the box. The third box is the one that gave me some trouble. There are a number of selections available, but what works for me is the one naming my sound card followed by "Wave". The last menu box is a choice between Stereo and Mono. Audacity set three of the boxes for me. In the third box I did have to select 'wave'. However, when I downloaded the newer 'beta' version of Audacity I did not have change any settings. If you have not used Audacity there is an online manual that can be useful.

To record you simply click on the reddish round dot whenever you are ready.
