I am trying to achieve an function that will be triggered with Sound beat, like Beat Saber(which is VR game; outside of Roblox platform). So when Sound does this:
You could try using the PlaybackLoudness property of the sound in relation to the sound’s volume, because its PlaybackLoudness is dependent on the sound’s volume
This is not possible sadly, PlaybackLoudness is not an audio signal, it is a value that updates once per frame. Try suggesting this in feature requests, as I agree that it could be useful.
