Dynamic Waveshapers

Post by Rocko »

Just revealed the world of Waveshapers... Awesome ;-) Gee I have som much to learn ;-)

I'm thinking of designing a waveshaper that has some sort of dynamic response, like a compressor. In this case I could have controls over Attack/release.

Example:
Say I want to 'heavily waveshape/distort' a guitar 'strum' but not process its 'peak' just at the beggining of the strum. How can I achieve that?
With a compressor I could 'not process the peak' by dialing in a longer attack. But How can I build this chain with a waveshaper which has a constant function (example: tanh(x) )


What should be the signal flow (block diagram / components) to acheive that ?

You can have waveshaper where you multiply the input by some gain and divide the output with the same gain. The output is constant volume, but the change changes how hard you drive the waveshaper. You can then hookup that gain to some sort of waveshaper. Here's a crude quick example - it kind of does what you want, just needs a lot of tweaking.
