AUDIO CUE

An audio cue is created by dragging an audio asset into a layer on a timeline. The cue shows the name of the used asset and a rendered waveform representing the audio signal level in the audio cue.

Right-click on the cue to open its context menu. From there, you can apply effects like Fade In , Fade Out or Volume to the cue.

In the CHANNEL MAPPING section, in the Cue Properties, the routing matrix of cue channels to audio buses is set. Each cross-point has a default value, indicated by a purple checkmark, that is set to the variable cueVolume. This corresponds to the value of the Volume tween.
This can be changed to a static value, another variable, an expression or a combination of all. To open the cross-point parameter field, click on the three dots inside the square. Close the field by pressing Enter.
