Hello guys. I'd like to make my background react to audio so when the audio is lower then the background turns black & white but when audio is higher the background turns to its normal colors. Right now I am using the Black & White effects from colors and presets, the effect has opacity so I guess a simple expression would do the job. I tried using this expression :
x=thisComp.layer("Sound Keys").effect("Sound Keys")("Output 1");
linear(x, 0, 100, 0, 150)

But this expression does it vice versa on how I'd like it.

On a quick glance, reversing the last values to something like

linear(x, 0, 100, 100, 0)

should do it.
