Trapcode Sound Keys

Main Controls

Audio Layer selects the layer from which to get the audio.

Channel selects Left or Right audio channel. Mix will use both.

Use Comp fps, when checked, will generate one keyframe per frame. When not checked, the Keyframes per Second parameter sets how many keyframes per second should be generated.

Apply, when pressed, generates keyframes for the work area duration for the active range(s).

Delete, when pressed, deletes all keyframes in the work area duration for the active range(s).

Cancel can be used to cancel an Apply command. Delete commands cannot be canceled (they are normally fast). All commands can be undone using Cmd + Z on Mac or Ctrl + Z on Windows.
