I have a Focusrite Scarlett 2i4 with a SM58 Shure microphone.  This is a dynamic microphone, and I know condenser mics are preferred for recording, but is that really why I end up with significant amounts of white noise in the recording of audio?  I have learned to use the noise remover tool in Edison (Image Line plugin) but with this process I end up taking some high end off the vocal that should be there.

So, might be a common problem, but how do I fix A LOT of white noise appearing in my vocal recordings?  Is it possible to have a completely clean recording set up? I'd like to hope so

Some synths, like sylenth, can have pretty harsh high frequencies that don't sound too great.  Seriously, anybody just go ahead and play the init preset from sylenth and focus on the high frequencies... you might start squinting.  So cutting those and replacing them with a white noise can help clean up the sound and make everything sound a bit cleaner and more straight forward.  The Only Way Is Up by Martin Garrix & Tiesto is a good example of a track that utilizes white noise as the high frequency filler.  Audien also gave this tip in his video where he talked about creating the synths in his track Wayfarer. 

I think the most important mixing strategies to use when using white noise are:
1. High pass! I think a high frequency, hiss-ey white noise sounds best... theres a lot of mid and low in a white noise oscillator that can sound cluttered in a mix.
2. Level it as best you can! Sometimes you can get away with the white noise sounding very present in the song (i.e. the track I mentioned) but usually if it's leveled out evenly with the synths, it'll sort of blend in and help fill out the sound without being too overbearing.

Transient shapers are fantastic tools.  First, for getting sounds with sharp attacks that "punch', I HIGHLY suggest Supercharger by Native Instruments. I was fortunate enough to get it for free because over the holidays a year or two ago they gave it away as a gift when they introduced the plugin.  It can take a snare and make it so "attack-ey" that it will turn into just a *click* sound.

Go to the plugin "Transient"
It's a free plugin that does the job of the one mentioned in the post above^ I have never compared the two but I think this one works well.

Here https://mega.nz/#F!v8oHCLza!SqPtonX0xbfz5eXqKFdZ6g and Here https://mega.nz/#F!fpQU1AgB!LTd7xXldeRJrsLvwUi-KIQ are a pretty huge amount of pop and rock song acapellas from the past few decades. I've barely downloaded a fraction and have enough remix material for the next couple years

Epic.

I was just listening back to a WIP that uses a supersaw lead that I'm fond of so I'll just describe what I have here.  6 layers.  3 Sylenth, 2 Nexus, 1 3xOSC.

I started with a scream-ey, square sounding lead in sylenth for the melody.  I duplicated it and kept the filtering, internal FX, etc. the same but changed some of the oscillators to more detuned saw waves with some panning.  I duplicated the synth again and added oscillators in higher octaves, different detune-ing, different panning.  1 layer of a harsh lead from nexus in the lower register to add more body.  another nexus lead with a very electronic sound that has stereo shaping to make it sound very wide.  In case you're not using FL Studio, 3xOSC is just a simple plugin with 3 oscillators, and im just using it for very high passed white noise that follows the same pattern as the melody.

EQing, reverb, stereo enhancing, etc. on the mixer channels.  all leads are grouped to a bus that is further processed.  and i'm very happy with my result 

As everybody has said, clipping the master tends to be a "no-no" but clipping individual instruments can add distortion that can be harnessed to create something pretty unique

Interesting concept.  Hopefully this will end up good for credibility.

Challenge accepted.
