Positions an Audio Source object onto the Spline point that’s closest to the camera, and within the Spline’s area. As a result, the follow the camera around whilst being restricted to the Spline curve.

This provides the impression that the Spline itself is emitting audio.

The functionality does have a limitation, it does not work well with concave Spline curves. The audio source may jump from Point A to Point B (and vice verse) as the camera moves around. This is because either point could be closer to the camera.
