im so lost, ive got all of my recording equipment already(mic, mixer, monitors, computer software) but i am running my mixer into the 1/8 inch mic input on my computer with a stock soundcard(dont know what type it is), i need to know what to buy to connect my mixer to my computer. Do i buy the best sound card with 1/4 inch input on it, or do i buy some type of digital box that has RCA stereo input and plugs USB to my computer? thanks in advance, any advice will help.
