[sdiy] Replicating a Wah spectral response with DSP and 0-5vdc pot control ?? Possible solution..

[Andrew Simper]

Modelling a linear version (no drive) of a wah is pretty straightforward.
Accurately modelling the non-linearities would be a lot more involved. Here
is an in depth paper on the topic:

But if you'd like more introductory material you can check out my web page
