Linking rotation parameter to a rate of speed rather than a fixed degree?
Hello!
I am attempting to control the speed that a layer rotates at using audio volume (audio boosts, layer spins faster)
I know how to link audio keyframes to a parameter- but the problem here is that by default in after effects you tell a layer to rotate by specifying a fixed degree value rather than a constant rate of speed that produces continuous rotation
Is there a way that I can link the rotation value of a layer to a constant cycle, and then modulate the rate of that cycle by linking the speed of the cycle to the audio amplitude?

So you want the layer to constantly rotate, but speed up and slow by by the multiplier?
Try this:
effect("Slider Control")("Slider")*thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")*timetime will keep the layer rotating, but multiplying it by the audio amplitube with a slider control to make the values larger should do the trick.
Alternatively:
(effect("Slider Control")("Slider")*thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider"))+timeHas time act to constantly rotate the solid, while additional rotation is provided by the audio amplitude.
I tried out both the first option seemed smoother.
