Wwise SDK

You can use Real-time Parameter Controls (RTPCs) to control specific properties of various Wwise objects (sounds, containers, control busses, effects, and so on) based on parameter changes that occur within the game in real time.

Here are some examples of how you can use RTPCs in your games:

• 레이싱 게임에서 자동차의 속도와 엔진 RPM에 따라 자동차 엔진 소리의 음량과 음 높이를 제어할 수 있습니다.
• In a ski or snowboard game, the sounds of the skis can change with speed and angle.
• In a scene located in an outdoors environment, you can tweak the parameters of an effect based on wind speed.
• You can randomly position sounds across multiple speakers. You can use your own random positioning code to drive RTPCs on the left-right and front-rear panning of 3D user-defined sounds, instead of using pre-defined paths created in Wwise.

In addition to the examples listed above, you can use RTPCs whenever you want an audio structure's property to be affected by what happens in a game.

The sound designer defines the names and ranges of game parameters in Wwise Authoring. Sound designers also define RTPC curves. 게임 매개 변수 값은 RTPC 곡선의 X 축에 나타납니다.

After the sound designer defines the game parameters and RTPC curves in Wwise Authoring, the game only needs to update the value of the various game parameters while the game is being played. Wwise는 게임 매개 변수의 현재 값에 대한 RTPC 곡선을 평가해 속성 값을 계산합니다.

See Working with RTPCs for more information about RTPCs from the sound designer's point of view.

See 통합 세부사항 - RTPC for an overview of RTPC integration.
