i just wrote a bigass article similar to dobro's, but the site logged me off and deleted my post, i will sumarize:
FFting things is very dangerous and can seriously screw up recordings. unless you are extremely knowledgeable about how and FFT filter operates, do not attempt to use it, except PERHAPS, if you are very confident it does not hurt your recording in ANY WAY AT ALL, you can MAYBE use a preset
a carefully-done 31 band EQ should take any mic rumble out of the mix, but anyone with a condenser should have a shockmount with it, and unless people are bumping the cable, mic, stand, or are jumping around while your laying tracks down, there should be no or almost undetectable mic rumble, if a proper shockmount is used correctly.
you should NEVER and i really mean NEVER have to amplify a track by more than a dB or two. one of the first things i really learned in the recording industry was the louder you get the raw track, the better your signal-to-noise ratio is. so, boost each input's signal as high as you can get it (without clipping the channel). this may clip the master volume meters, and if so, you can turn down the master fader-but at least your noise (that is inherent in recording) will be a solid 40 dB under the strong part of your track right?
compression is helpful about 85-95% of the time, but most of what compression is for is to make things stand out in the mix, so it does not seem appropriate hear UNLESS: as boogieman said, compression should not be noticeable, it should smooth out the peaks. if there are nasty, noticeable peaks in the track, you could compress that very top-end, otherwise a very careful expansion may be suited if you really want these vocals (not a vox, that sounds like some yamaha synth shit, not the most natural musical instrument in creation-your voice)
of course, after you have done everything you are going to do to the raw track, you should level it to where you want it in the mix, good job there, boogieman.
two more comments, first, what about reverb? reverb is this worlds best way to smooth somthing out and make it float into the mix and round itself out. don't bother with CEP's quickverb, i did for a while, but it just doesn' have the quality that the reverb and full reverb effects have. i would highly recommend using the full reverb effect (which can be put to a very light setting if desired) and clicking 'prepare now' so that you can use it in the multitrack (you may have to lock the track, if your computer can't handle the processing.
Lastly, (i could barely restrain my laughter about this one):
da fuck is a clean eq? the very definition of clean is that there are no delay effects, filters, or processing of any type on the track, it is just the raw track, with panning and volume added if desired. panning and volume are the ONLY things you can do to a track and still call it truly clean. perhaps, boogieman, you (and whoever you work with) have come up with another meaning for the phrase "clean EQ," which is fine, i have done that with many, many things, but i don't just start throwing them out into public forums without explanation. you either need to explain yourself on this one, or given by the rest of your post, either get LOTS of help about how to do recording and post-production, or get LOST from this industry by the time your done reading this.
