Are high sample rates better for DSP? Options

[Ethan Winer]

I've read many times that audio plug-ins such as equalizers work better at higher sample rates, even if audio generally doesn't benefit. It seems unlikely that there's a practical advantage to up-sampling all your files, or recording at 96 KHz in the first place, but is there a potential theoretical improvement? Or is this just another Internet myth?

In addition to the warping one sees in a bilinear mapping (which is what this warping you people are talking about is), anything that does any nonlinear processing must do oversampling at least as big as, or larger than, its maximum polynomial order.
