)

Remarks

This can be used in place of "play" when it is desired to fade in the sound over time.

If FadeTime is 0.0, the change in volume is instant. If FadeTime is > 0.0, the multiplier will be increased from 0 to FadeVolumeLevel over FadeIn seconds.

Parameters

Parameter	Description
FadeInDuration	how long it should take to reach the FadeVolumeLevel
FadeVolumeLevel	the percentage of the AudioComponents's calculated volume to fade to
