title pretty much says it. an example is recording acoustic guitar and vocals, each with a separate mic, into separate channels on a usb mixer, into my pc and into audacity. now i dont want just one combined teack of sound, i want to separate ones for mixing purposes. is there a way to do this? also ive never used reaper but i just got it so if its possible in there and not audacity and help is appreciated.

thanks all
If your usb mixer really is a mixer and not a multi-channel interface, you're SOL

Also, switch to Reaper and never look back
