This question already has an answer here:
I recorded some spur of the moment interviews using my DSLR at an event. The people I interviewed came out well enough for my ears to discern what they are saying, but there is a lot of background conversation "noise." Most of it isn't perceptible words, but it is loud enough to be distracting. I've tried Googling the issue and most of the noise reduction suggestions I've found seem focused on removing air conditioners, music, etc.
I think the challenge I'm running into is that I'm not trying to remove sound that is significantly lower in frequency. I do have several really good seconds of pure background sound recorded that I've tried to use as a sample in Adobe's "noise reduction (process)" tool. Actually Final Cut Pro X's automatic noise reduction was probably better at isolating the real conversation, but ended up creating a terribly tinny result.
Can anyone offer advice on how to specifically reduce the volume of background conversations in Adobe Audition CC?
