I have a Macbook, Garage Band, and a two different piano keyboards. I want to record some of my own music on to Garage Band. It sounds like crap when I record it using my built in computer microphone. I went to Guitar Center today to see if I could get some more information about how to record it, and I was overwhelmed with all the options and lingo that the man was telling me. How do I get good quality recordings onto Garage Band? What all would I need to buy to get it done? Is there a website that can give me a ton of the basics of audio recording? Thank you very much fellow musicians!
