Need help animating light intensity to audio
I am working on a project for my church and we want to have a lighted ball pulse to a voice clip. Any ideas on the most efficient way to get the pulse intensity linked to the audio to make it seem the ball is talking?

OK, what you can do is something like this.
For your audio layer, convert audio to keyframes.
Right click, Keyframe Assistant, Convert Audio to Keyframes.Then, create a solid and make it 3D.
Next, create a point light and move it out in Z-space so it only illuminates the center of the solid.Next, create an expression for the Light Intensity that uses the linear function.
Something like this:
linear(thisComp.layer(“Audio Amplitude”).effect(“Left Channel”)(“Slider”),0,10,25,100);Where thisComp.layer(“Audio Amplitude”).effect(“Left Channel” is one of the audio channels that’s been keyframed.
The Audio Amplitude is a null that the keyframes have been applied to.
Play with that and you should be on your way.
