Greasy Fork

Works great, but the range was still not enough for me so I created a modified version that makes it *actually* exponential - 10%=10dB: https://gist.github.com/Barteks2x/a4e189a36a10c159bb1644ffca21c02a . Works really well on firefox on linux, pulseaudio volume control confirms it's working correctly.

Update: I ended up using x^3 after finding out that pulseaudio does it, which is equivalent to setting the exponent to 3, and also modified it to make it based directly on the slider if it can be found.

Thanks for sharing.

I incorporated the new exponent in a new version of the script. I figured that the janky volume slider changing behavior has no relation to rounding issues and just happens sometimes. so there is no reason to hold back there.
