can I run my audio into a usb type device straight from my mixer or do I need an audio interface. I'm trying to record audio in that program "audacity" and then export it as an MP3. Can someone give me some tips here. thnx Right now I'm trying to record from mixer to a 1/8th jack into the mic input. I don't have a special sound card either. Just the one that came with the computer. I can record but it sounds like rubbish.
