Since it is applied to objects in the setting hierarchy, it affects the lower hierarchies like other parameters.
For example, setting AISAC in a Cue will affect all tracks in that Cue.
If you want to control the blending of each track with an AISAC, set the AISACs for those tracks to use the same controller.

AISAC can be set on the following objects:

Cue
Track
Category

Application of AISAC

3D Positioning allows you to apply AISAC parameter changes depending on distance attenuation and the relative angle between the listener and the sound source during playback.
If you apply it to distance attenuation, you can change the attenuation curve for each sound and the effectiveness of effects such as reverb.
If you apply it to a relative angle, you can create position-dependent changes in how the sound sounds.

You can also apply AISAC via REACT by specifying AISAC control for the change parameter of REACT.
By setting a graph that changes the pitch in AISAC, which works in conjunction with REACT, you can create effects like bullet time.

AISAC's scope does not go back to the top

Even if there is no audible difference, performance and data efficiency may change depending on where the AISAC is placed. For example, if you want to change the volume of each track at once, it is most efficient to specify them in a Cue if the changes are the same.
Only set this for a track if you want to set individual behavior for that track.

The "playback rate" that changes the Cue's timeline processing speed should be set in the AISAC that is set for the Cue.
Setting it on a track does not affect Cue playback as it is not retroactive.
(This will affect lower levels such as Cue links called from tracks.)
