Do I have to have Noise Reduction?

I have some scenes in my short that have incredibly annoying hiss/hum mic noise. I've been playing with the EQ to get rid of it, by manipulating the frequency levels. This seems to be affecting my overall volume levels. (I guess I'll mention here that I know absolutely nothing about audio. Nothing.)

So my questions are- should I worry about the volume levels, or can I just kinda fix it with a volume envelope?

Should I do this "fixing" to the track before I string it together with other footage, or do it after I'm done with the cutting and pasting of the scene?

After I render, can I still fix it further or will it just make it ridiculously muddy?

Any help would be greatly appreciated, my learning curve is sooooo steep!

Thanks, Kia

It's all a matter of playing around. Hum can be reduced with low eq, and hiss with high, but each may take out too much of your wanted signal to be acceptable. Using the track effects noise gate might be a good compromise. Volume envelopes are laborious but very controllable.

Or you could get a noise reduction plugin, at a range of prices. Waves ones are excellent and easy to apply, but expensive. Others vary in effectiveness and ease of use. Any one of these may help, but will also take some of the wanted signal too (but less than straight EQ).

I like the "defaults" in sofo's nr2.0a; "educational" as well...
