: "AISAC" is a mechanism that enables the user to create sounds that change interactively like an automotive engine sound.
AISAC converts the "AISAC control value" provided from the programmers into multiple playback parameters such as volume or pitch.
The sound designer creates graph that converts these control values to the sounds using the authoring tool.
Since the designer can create this conversion graph while previewing it on the authoring tool, the designer can create the interactive sound without involving the programmers during this tasks.

: The user can also control the start and stop of the sound playback using Play Gate parameters of AISAC.
The user can configure the AISAC control value in such a way that playback starts when the control value reaches a certain value, and stops when it reaches another value.
For example, the user can create a sound effect on a certain object so that the sound stops when it goes far away, and the sound resumes when it approaches closer.

In addition, the user can express the change of parameters on the time line using AISAC modulation.
For example, the user can express the increase of the tension in the application by designing the environmental sound such as a cheering to be changed in accordance with the time progress.
