Apple Shake 4 - Manual (Page 286)

286 Chapter 9 Using the Audio Panel
The parameters located in the Create Curves subtree let you analyze the current audio
mix, creating a keyframed curve that’s stored as the Audio parameter, within the
localParameters subtree of the Globals tab.
The audio parameter can be referenced as an expression from any other parameter in
your project.
To create an audio curve:
1 Open the Audio Panel, and import one or more audio files into your project.
2 Open the Create Curves subtree.
3 Click the Update from Globals button to set the time range to be analyzed to match
the timeRange parameter of your project.
4 Adjust the other Create Curves parameters as necessary (see the next section for more
information).
5 To create the audio parameter, click the Create Variable Under Globals button.
