What’s the Deal with Summed-Input Stereo Effects? – Quilter Laboratories:
Recently, there’s been a lot of controversy about effects that use summed stereo inputs vs. independent inputs. Obviously, nobody wants their stereo signal unintentionally collapsed to mono. So, effects with independent stereo inputs are clearly better, right? How has this gone unnoticed for decades and is only now exposed as a cost-cutting measure to cheat unsuspecting consumers?
Except, that’s not what’s happening here — not even close.
In this blog post, I will explain how stereo effects are designed, why they are designed this way, and the source of confusion around channel summing. I will also explain where channel summing might actually be desirable and where it’s not.
