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.
