  Create Audio Amplitude with ExtendScript – no mouse clicks

  Posted by Martin Bollerup on February 14, 2013 at 10:24 am

  Hey guys

  Is there any way of creating the Audio Amplitude layer with ExtendScript only? This should be done with no mouse clicks as it is a 100% automated process.

  If you’ve got any alternative ideas – such as using the Audio Waveform Effect to manipulate a Solids color from white to black and then get the amout of black as a value from 0-255 or 0-100 or 17-17.3. Or extracting the waveform to a vector path and then measuring the height of the element?

  thanks
  Martin

  You can execute this command:

  app.executeCommand(app.findMenuCommandId(“Convert Audio to Keyframes”));

  If you have CS6, you can make sure your comp has focus and the layer is selected first, otherwise you have to do that by hand.

  myComp.openInViewer();
  myComp.layer(1).selected = true;

  A related curiosity: if activeItem is null (because timeline or viewer don’t have focus). Is there a way to use openInViewer to give focus to the comp that’s already open?
