Unwanted noise removal
Sending a project out for mastering soon. The mixes came out amazing, though there are a few things I am wondering if mastering will be able to address.
I am having an issue with some "noise floors" turning on at weird times. For instance, a song where the guitar starts the song, and after a few bars is accompanied by the vocal...right before the vocal comes on though, you hear the added noise from the mic coming on, before the first breath and note. Once the voice comes in, it sounds great, though that second of noise is distracting. this was something that wasn't addressed in the mix.
In another song, the noise is particularly loud during a verse where there is just a single guitar, bass and drums, and a pretty hollow sounding groove; the noise is audible here more so than I'd like...whereas most of the other parts of the song, the band covers up any audible noise, this song the noise is present.
Is it possible for a mastering engineer to clean this stuff up? I am assuming any unwanted noise at the beginning and end of the tracks will be easy to clean, though the few moments of noise in the track that are distracting...am i stuck with them? not a huge problem, but a minor detail i'd like to get cleaned up if possible.
