Over the weekend I filmed a sketch with two actors. The recording was done with two lav mics; one a Rode and one a cheapo one. The actors were sat fairly close to eachother and the cheapo mic has picked up the other actor's voice a bit too much, causing reverb when I put the two tracks together (which are definitely in sync).
How can I reduce the other actor's volume in the track from the cheapo mic without much affecting the volume of the actor that it's supposed to be recording? I have Audacity and Adobe Audition.
Note: Fading the track in and out might not be an option as it carries a fair bit of other background noise, which would make the fades distracting.
