Hi I have a couple of questions... Let's start with the latter: (1) How does a guitar amp distortion effect deal with aliasing. If you use a transfer function like tanh, you get lots of high frequencies well beyond nyquist. How do commercial products like:
http://www.loopblog.net/tutorials/plugin-tips/effects/best-distortion-plugins-2012/ handle this problem. I'm guessing they use the oversample/filter technique? (2) How taxing is that on the CPU? Can a modern day i3, i5, i7 handle this sort of thing with ease? Is there some simple rule of thumb that can help calculate how much more CPU processing power is needed depending on the oversampling factor?
