virtual void FadeIn
(
float FadeInDuration,
float FadeVolumeLevel,
float StartTime,
const EAudioFaderCurve FadeCurve

This function allows designers to call Play on an Audio Component instance while applying a volume curve over time. Parameters allow designers to indicate the duration of the fade, the curve shape, and the start time if seeking into the sound.
Parameters
| Name | Description |
|---|---|
| FadeInDuration | How long it should take to reach the FadeVolumeLevel |
| FadeVolumeLevel | The percentage of the AudioComponents's calculated volume to fade to |
| FadeCurve | The curve to use when interpolating between the old and new volume |
