back & forth movement linked to audio
Hi,
Very new to Expressions. Searching past posts, I think I know part of this, but I’m missing something. I need to make a word slant back and forth, synced with music. When I use a straight expression linking to audio, it only slants in one direction. I believe I need to use an expression tied to a slider, but can’t quite figure out how to set a range of values so that it goes back and forth but also is linked to the audio channel keyframes? Can you please steer me in the right direction? Thanks!!

It depends on what you’re doing exactly, but it might be something like this:
aud = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
audMax = 20;
linear(aud,0,audMax,-30,30)Dan

Thanks for the reply, Dan! So I won’t be using the pick whip to link to the audio channels, just straight up Expressions? Let me try this and see- thanks so much!

Usually, (and I think that’s the case in your situation) you’ll need to remap the audio values to a range that makes sense for what you’re trying to do. That’s where the linear() function comes into play.

Yes, you’re right. That works perfectly! Thank you for untangling the problem for me- makes much more sense now!
