Hello everybody!
There is a question of how to make a directional sound, What do I mean.
There is a tour in which there are 2 videos, how to make the video start to play when the user looks at the video in a range of 10 degrees. And the second video is stopped, but when the client turns the panorama and goes to another video (1 stops and the second starts to play) I did not find the forum I could not find the question I'm asking badly.
Tell me please.

Hi,
Im going to make the assumption that these a pinned videos on a TV.
Do you really need to stop and start the videos?
I ask because the simplest thing to do is just use directional sound but limit the sound field so you only start to hear the sound within the limits you require.
Regards,
Hopki

Hi, Matin! Me to limit the sound. Example 360 panorama in it there are two sound source. I want to make it so that when I turn to the TV I listen to the TV and after 90 degrees I will hear another sound source.
