Analytic expressions for (messing with) potentiometer tapers anyone?

[ChopSauce]

Those guys who show plots of potentiometer tapers, how do they compute that?

I manage to mess with alpha pots to provide me with the tapers I need without having to re-drill the chassis to 3/8", & I'm rather (*) wrote my own Python scripts to compute the tapers myself. I need the analytical expression for tapers to do that.

Any clue?

(*)Amongst other usefull ressources https://www.diystompboxes.com/analogalc ... h/emh.html provides a calculator to help with it, but I'm not able to see how the outcome exactly behaves with the closest standard resistance values - for example.

Have you run across this resource?

There is an explanation for the different pot tapers commercially available. It appears the Alpha pots use linear approximations to produce a "logarithmic" curve.

Yes, I've seen that too, great link, thanks!

I'm still missing the maths for the theoretical curves, though.
