How to separate interviewee and interviewer from background chatter and clatter

[good_knight]

Have made several Premiere Pro 2-hr movies, the last 2 for YouTube. First time using Audition.  Original av clips are MTS, 6 channel 48 kHz 32 bit float. Media Encoded to MP4 stereo for keywording and for YouTube.  Need to clarify the interviewer and interviewee from the background chatter and clatter. Tried Effects .> Noise Reduction / Restoration > Capture Noise Print ... Noise Reduction. Got a little improvement, but want much more, even possibly background mute. Audition offers a miriad of effects. How do i choose the right path? Should i start with MTS 5.1 or with MP4 2 channel? Thanks!

First of all, the original 6 channel source: are any of those channels cleaner?

Secondly, the noise reduction often works best with several "gentle passes". Also, eq can help to remove unwanted noise outside the speaker's range.

Adobe Podcast can help, but because it re-synthesizes the voices, things can get weird.

And there a number of third party plugins that can help. Waves Clarity, dxRevive, Acon's extact:dialogue, Supertone Clear, Crumplepop Audio denoise. Many of these have trial versions.
