I have a problem to find a correct Algorithm for calculate
value in the interval [0,1] using a Slider in the interval [0,84]
The slider is used for control an Audio level.
The ideal volume slider follows an exponential curve,
value between zero (silence) and 1.0 (maximum).
I need to find a logarithmic function that produces
value with trend similar to that of the attached graph.
Using SliderX / sliderMax I get Linear variation, but
I need exponential values as in curve graph.
Any suggestions will be well accepted.
