Typically i just think about my songs from a half-ass mono perspective, do subtractive EQ'ing to make sure all the sounds play nice together, put my kicks/snares/sub bass in mono, sometimes I modulate panning left to right for ambiance, then i'll use Nugen Stereoizer on pads + cymbals sometimes and i basically leave all leads + other sounds as-is. But to be honest I've never given stereo spread much thought aside from that before. I've been googling for articles and reading up on stereo spread, came across the "wall of sound" mixdown style. After thinking that I understood the concept, I started trying to think of creative ways to incorporate stereo spread into my songs and eventually I really confused myself. What does double-panning accomplish? (duplicate a track, pan one all the way to the right, the other all the way to the left) How does that differ from using a stereo spread like Nugen Stereoizer or iZotope Ozone's Stereo Imaging? How do those differ from using a M/S tool like Mathew Lane's DrMS? (or maybe iZotope Ozone's Stereo Imaging falls into this category, I'm not sure) I'd used Mathew Lane's DrMS' before and it didn't have the same effect as Nugen Stereoizer. It seemed like when I spread the sound out with Mathew Lane's DrMS, the sound itself lost a lot of its character, as if DrMS muted the sound's mid signal and boosted the sound's side signal. At least that's what I assume. Whereas Nugen Stereoizer was great, the sound didn't lose any of its character as if Stereoizer kept the sound's full mid/side character and just stretched the mid signal to the sides somehow. I'm not sure what Nugen is doing but it sounds like a stereo widening without losing any M/S information. I'm confused at all these different ways of messing with the stereo spread because there are only 2 channels for a signal - the left and right sides. I realize these methods incorporate the mid/side processing where the mid is only the sound that is identical in both left and right channels but I'm still confused trying to get my head around these different methods/tools.
