    Here’s the trick: record in quad.

    In Audacity, invert either the front or the rear track.

    What happens is that the ambient noise which hits all four mics about equally is significantly subtracted out, leaving the voices (which are significantly different between front and rear mics) synchronize out.

    Works really well, I was amazed.

    flattr this!

      You can do the same trick with the 2-channel surround. I point the front (90º, narrow) mic to the interviewee and the back (120º, wide) mic to me, Then I use the free Voxengo MSED plugin, removing the side signal. You get a stereo track with similar channels. Just use one of them.
