Hey Guys,
really hope somebody can give me a hint on this one:
I need to control the volume of an Audio-Out node related to a linear input in a non-linear way.
My input value is a floating number between 0.0 and 1.0. Normally I could simply map it to my output value of -100 dB to 0 dB. Drawn as a mathematical graph, this would show as a straight rising line.
But this time I would prefer to create a different behavior:
When beginning to raise the input value (eg. between 0.0 and 0.3) there should be a significantly stronger increase in volume than when raising the value at the end of the input scale (eg. between 0.7 and 1.0). As a graph this would be a curve similar to this one:

How can I do this? Is there maybe even a way to create a GUI element similar to curves-control in Photoshop to control my curve?
Any suggestions are highly appreciated…
