Using audio to drive noise

I currently have a filein SOP containing a 3D OBJ plugged into a noise SOP, which is distorting the vertices of my object. I’ve been attempting to use an audio file (or eventually audio source) CHOP to drive this noise animation in realtime, but I’m not sure how to get the audio output into my noise SOP. Any help would be much appreciated!

One way you might think about is plugging your audio into an analyze CHOP, commonly set to RMS, and exporting that value to a parameter in the noise SOP. Matthew Ragan has a lot of great tutorials on working with audio in TD.

exactly. i’ve achieved a similar effect like this:

Beat or Analyze CHOP → math (to control min/max) → lag (to control smoothness) and then exporting the value into the Amplitude parameter of the noise SOP to create a nice pumping effect.
