Can I Use One Audio Track to Reduce/Remove Background Noise in Another?

Question

Hey everyone, so here is my problem: I was recording an interview for my podcast, and I burp at one point during the interview--yeah...its embarrassing and I'd like for it to be removed. I record my interviews through Zencastr.com. Zencastr provides me with three audio tracks when I'm done recording:

1. The audio from my end

2. The audio from the guest

3. The 2 tracks combined into one

The burp shows up on all three including the audio of only my guest since he did not have headphones plugged in while doing the interview, so my audio bled through over to his end.

So, my question is: is there a way for me to isolate the burp on the audio of just me, and use that to reduce/remove it on the audio track that includes both of us. This is not something that I can easily delete from the audio track of both of us since it happens while my guest is in the middle of talking.

Thanks for any help anyone can offer.

Almost certainly the best way to deal with this is to paint it out very carefully in spectral view, where what's different about the noise compared to the speech should be fairly obvious. To find out whether this is really practical or not, you'd have to upload it somewhere so we could look at it and see, but usually with noises like that it's possible to reduce them significantly without disturbing the speech excessively (or sometimes even at all).
