I'm trying to linearize the output of an audio tapered potentiometer. Right now, I'm using ADC on a Beaglebone to read the value of a 250k potentiometer with 3.3V. I get a value between 0 and 1, but it is scaled such that the rate of change of the potentiometer's value increases dramatically as the knob is turned to the right – it looks something like an exponential curve.
I was wondering how I could convert the value of the audio tapered potentiometer to that resembling a linear one. Can I just do something with logarithms?
