Is there any reference for this moving_audio generation function?

moving_audio = (1 - interp_weight) * start_audio + interp_weight * end_audio
Is there any reference for this moving_audio generation function? Are there alternative generation methods?

When I was generating the dataset, I noticed that the starting point of the speaker's location appears outside the map. Was this intentionally designed?

the printed point is below

def random_select_start_end_points(scene: Scene, distance_threshold: float = 5.0) -> T.Tuple[np.ndarray, np.ndarray]:
    start_point = scene.sim.pathfinder.get_random_navigable_point()
    end_point = scene.sim.pathfinder.get_random_navigable_point()
    print("start_point, end_point", start_point, end_point)
  
Sample output:
start_point, end_point [ 6.932141 3.5141459 -2.331494 ] [11.820602 0.11414599 -0.2524432 ]

This is probably due to different layers. Since it's random, it's not easy to control. You can try to minimize the distance to keep it within one layer as much as possible.

Thanks, can the different layers be understood as the process of automatic navigation going through different floors?

I have tried different heights, even zero, but there are still navigation points appearing outside the map, which is very strange.
