I have a new version out, v1.0.8, it's all about optimisation, the performance can be up to about 25% faster (mostly at high precision settings). I really don't think it can be optimised any further short of using a much faster FFT routine (I don't think there's any such routine) or doing it on the GPU (and then again it wouldn't necessarily work faster).

Yeah I'll do that. Someone mentioned to me a way to do M-S editing already, thought I'm not sure I understand how it's done. It's about using a "Mid-Side matrix" to split the signal into two "groups" (I don't know what that is), pan each group to the left and right respectively and have two instances of SplineEQ on each group and then combine the outputs back together using another Mid-Side matrix.
I have no idea how to do any of that though, I don't get how a plugin can split into two "groups".
