Control audio volume with expressions

[Todd Kopriva]

There are some examples here, including a really nifty one by Nathan Gambles that ducks the audio of one layer in response to the audio levels in another layer.

Hey Todd,

Thank you for that resource. Looking through all of them I can’t find where someone controls the volume of the audio layer. Basically what I want to do it create an expression that will use values from a null layer to know what volume a specfic layer shoudl be at. So I guess what I am asking is what is the code I need to adjust the volume.

I thought it was something like:

thisComp.layer(“Audio Layer”).audio.audioLevels

but it is giving me anything. So how do I access the audio level at any given time? Thanks

As I said, the example by Nathan Gambles gives you what you need.

Don’t use Audio Levels. Use the properties of the Stereo Mixer effect, as Nathan does in his example.
