How to Sync audio to animation

[Graham Quince]

In the menu Animation > Keyframe Assistant there a tool called Convert Audio to Keyframes. This will create a Null Object with the keyframe values. Generally I find these keyframes are quite low numerically. You may need to use an expression to boost the animation.

Thanks I’ve tried this method but I didn’t use expression I’m a beginner could you please give me the expression which I can use for animation

I think the simplest method to explain is that if you expand the Scale property on the timeline and expand the Audio Amplitude on the timeline so you can see the keyframes.

Then use the Scale’s pickwhip (looks a bit like an @ ) and click and drag this onto the both channels’ Slider. This will have the scale link to the Audio keyframes and if you use the down arrow which has appeared next to the Scale, you will see this expression:

temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);

[temp, temp]

Click on it to edit and and add *10 (or whatever value) to the first line, i.e.:

temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)*10;

[temp, temp]
