My friend has a Mackie 32:8 that he wants to use to use for his recording studio. I'm not a recording engineer; I’m a PC tech. He asked me to find a way to record on his pc from his Mackie board. Do I need to get him a special sound card or interface card? Is there a USB interface he can use? What software would you recommend? He would like to keep the cost reasonable but any suggestions will be appreciated.
