Basically I want a mic and preamp that will go into my computer at thats it. I dont know a lot about this so basically what i need to know is the raw basics i need to record with half decent sound. I dont want it to sound like a cassette player but it doesnt have to be professional sounding either, im not worried about too much mixing. This is mostly for recording parts so i can write songs and hear them as i write without my band. I have an sm-57 shure mic i plan on using and ill be using my HP PC, eventually i want a mac but not any time soon. What else do I need? Any help is appreciated, thanks.
