I wanna do a little rudimentary home recording - nowt, flash, maybe just a couple acoustic guitar and vocal demos, and maybe a bit electric playing just to hear myself back when practicing. I've got an SM57 for micing up my amp when live, and I've got Audacity which I've pissed about with before. Now as I said I'm not arsed about quality being great and just wanting a very basic setup I had hoped I'd just be able to plug the mic into the computer and away we go but apparently that's not possible. Anyone know what I'd need to get going? Cheap preamp?
