Expression when audio reaches 0db
Hello guys!
I’m making some video classes and all of them have an audioform that reaches 0db from time to time when the audio effects and the song end.
When they reach 0db, I always have to change the text on the screen:
I just manually scroll one text in, and scroll one text out.
I would like to know if there’s a way to automatically do it, by setting an expression to control the position of a NULL object, and applying +360 on the null’s y-position, everytime the audio reaches 0db. And I would link all my text to this null, I would just arrange them 360px apart and the expression would move them all.
I don’t even know if this is possible, hahaha
Thanks!

I think that you would need an expression that would make your project very slow, because you have to test every frame for that start of silence. Imagine after about 10 minutes. Your expression would have 18000 frames to check. For one frame. If you had separate layers for each song, it would be a lot easier.

You could convert the audio level to keyframes (using the keyframe assistant) and then link to the Audio Amplitude Slider.
