Am I looking for a plug-in or...? I don't know.. O_o

Feeling totally lost. Can anyone point me in the right direction?

  1. I want to take an audio file, run it through… something… and have it output a video waveform. (As in, “I can’t use the video footage of this interview, so instead I want to see the waveform of his audio instead.”)
    What does that??
  2. Down the road, I’ll be livestreaming video interviews. When someone’s video feed isn’t available, I’d like to replace their camera feed with a waveform of their voice. What does that??

I’m working off a Mac. So far, using really basic tool. (Final Cut Pro X and Zoom.)
