When you are SFX editing placing effect like cars, horns, construction, birds, etc...
Say you have all of these recorded you've got them in a pallet of sorts and they are from different places. Some from a library, some personally recorded, and some from Wild Sound. Say for example they are all either in a city or a suburb meaning they have extraneous noise like city wash or other stuff.
When you prepare these SFX for print after the edit, do you make sure that they are Noise reduced? If they aren't noise reduced, do you use some kind of fitting method to make the mix fit into them?
What I've been doing is slight Noise Reduction and what I havn't been doing is dynamically EQing them to bring back some of the life. The result is a somewhat space monkeyed and less originally vibrant sound that has less background noise.
