In a game - where sound is played back interactively instead of linearly - it may sometimes be difficult to adjust the volume.

Problem	Situation	Result
You want to emphasize an important sound.	Many other sounds are being played.	Even if you increase the volume of the important sound, still mixed with other sounds. The sound cracks and is hard to hear.

However, by using REACT, you can temporarily lower the volume of the sounds from the other Categories. This is called a ducking effect.
You can specify the volume change over time, the trigger that starts the ducking, as well as which Category should have its volume lowered.

Three time ranges

Three time ranges are specified to use the Ducker.

Changing time

It is the time between the start of the triggering Cue and when the "change parameter" value reaches "change level value".
You can specify the mapping curve the level value will follow.

Holding time

It is the time where the level value is hold, once the changing time is over. There are two types of hold.

Type	Description
During playback	Maintain the level value until the trigger Cue stops. Even after the trigger Cue is stopped, the level value is maintained during the holding time.
Fixed time	Regardless of the stop state of the Cue, the level value is maintained during the holding time. A value of 0 will instantly transition to the "returning time".

Returning time

This is the time it takes for the level to reach back its initial value (before the trigger Cue was played back).
You can specify the mapping curve the level value will follow.
