Multi-device recording

Because I need to be able to record multiple, separate signals simultaneously, I have installed three separate sound cards, which show up in Windows and Audacity as three separate audio devices (as it should). I am using the line-in input on all three. My question is, is it possible to have Audacity record from all three separate sound devices (line-input on each card), simultaneously into separate audio tracks? I know that this is possible on a software/hardware level, as I have written and built my own programs that do multi-device capturing, but I wanted to know if Audacity could do it for me, as I enjoy working with everything in one application.

Thank you.

I don’t think Audacity can do this at the moment. You’re certainly right that it’s possible, but I’m not sure how much of Audacity’s code would need to change to get that option.
