If you're a PC person you can use Audacity to record and process the sound.
With a PC solution the question is whether your soundcard is up to it, and the major issue with PC sound is noise; the chipsets on motherboards and budget soundcards tend to be a bit hissy, although performance is improving all the time so I might be talking rubbish here.
An external soundcard connected via USB should have lower noise, so thats a possibiity as well.
