Well the first, and most important thing u should do with your vocals imo is edit them PRECISELY. Most people are just toooo lazy to properly do this or even learn how.. when i say edit i mean comb over every single word and phrase. Remove pops and clicks, odd mouth noises, lip smacks, rumbles, spikes...etc.. My vocal edits have TONS of lilltel millisecond crossfades,fade outs and ins, and cuts and other shit in them. Take advantage of that ZOOM tool and get all up in the nitty gritty of the vocal and take out what sux and leave whats good. It takes time, and patience, and a capacity to listen to the same shit over and over again for a long time lol. Seems like u dont really need it on first listen, but trust when u really critically listen to ur vocal take, even on a good one, there is bound to be alot of shit that the mic picks up that u didnt intend it to. Esp if u record at a home studio or less than ideal environment. eliminate dead noise in between verses and fade out the ends of verses. Trim the fat. It takes some skill to get really good and quick with it, but the results are dramatically improved. And u didnt even touch the eq or compression yet. U need pretty good monitors and a sensitive ear to do it well. I always edit with the vocal way louder than the beat so its easier to hear mistakes. If u can get it sounding good extra loud like that, then when u blend it in its gonna sound even iller. I dont have time to break down how to this step by step but try googling for tips related to what DAW u use. Or just start experimenting. Again im not even talking about plugin and effects, Im just talking about how PROPERLY use the basic audio tools cut,fade,crossfade,volume, nudge ..etc... I use pro tools and imo thats the best DAW for doing audio edits. I always tell people but they dont seem to believe me, that your vocals should already sound good before u reach for eq,verb,delay,comp ..any of that shit. Alot of little tiny improvements leads to a much bigger and better overall result.
