white noise issue

[allthatendswell]

Just finishing a session of recording some vocals. I noticed there was some un-wanted background noise. So I used a noise reduction plugin to take out the noise but now the quality sounds awful. I'm not 100% sure why this happened or how I can undo this. Any help?

Re Track seems to be your only option if the NR did not work.

ignore the bad mix, but you can hear what I'm talking about. I used the noise reduction from 1:02-2:16. then used it again 2:29 through the end
