location-sound Possible to split a recorder-mixed track?

Did some recordings the other day, in a rush as usual, didn't have time to scout a good location, and didn't notice that somehow my H4n Pro had the 1/2 Link and Mono mix turned on (I say somehow because I always record with it off so I can mix the mic's manually) It was windy but I can usually mix it out between the lav and the shotgun...
So now I have one file with identical channels, because both mics were mixed together in the recorder. I'm pretty sure I already know the answer, but is there any saving this? Is there any software that will somehow let me pull the two seperate mic signals from the one file?
