Try Goldwave,
www.golwave.com provided that the output from your sound source (whichever it is) goes to the input of your PC, this program will record, edit, apply some effects etc.
It is not freeware per se, but gives you an "amount of money" each time you run it, and you spend some each time you do something. (cut, paste, record, save etc).... when the money runs out it stops functioning nd you just have to launch it again.
Ii find it very helpful for simple working.
