This script was used in this tutorial at Aetuts+

This script will add markers, split a layer or add a new text layer with incrementing numbers based on audio intensity.

Usage Instructions:

  1. Select the audio layer and run the Keyframe Assistant “Convert Audio to Keyframes”.
  2. Run the script and choose which layer you wish to mark or split. If the layer you want does not show up, select the comp and press the Refresh button.
  3. Set the audio level at which the markers should be place. The script uses the “Both Channels” value from the Audio Amplitude layer which is created after running “Convert Audio to Keyframes”. A marker will place placed when the audio crosses that value and another marker won’t be placed until the audio drops below and above again.
  4. Choose one of the 3 output options:
    • Place markers on a layer
    • Split the layer
    • Create a new text layer with incrementing numbers

The layer will then be marked or split at the threshold points. If you choose to create a new text layer then the newly created text layer will have keyframes with incrementing numerical values which can be used to trigger expressions.
