Audio Syncro with babylon.js


Recommended Posts



 What would you like to do exactly? I'm exposing the _startTime property on the BABYLON.Sound object and you can access to the global Web Audio timer inside the Engine.audioEngine.audioContext.currentTime .


 So you'll have to compute it by yourself. But if I manage to understand your scenario, I can add some code for you.

Ok, thanx for the very fast answer!


I have a song 4min long, with two important scenes, where the 3D animation should be in sync with the song. The scene before the important moments in the song, its ok when it doesnt play thru the full scene before the important moment come. Its ok when the animation jumps on this point to the important scene.


10 scenes, scene 5 and 7 must be in sync but the scene 4 and 6 the animation can jump to the important scene when its not in sync.

Thanx, Alberto

I see internally, there is  _startOffset property, which defaults to 0.  Is set by pause() to the current spot, so that when play() is called again, it picks up where it left off.


Assuming no changes to API, maybe when your code jumps to a spot you wish to be in-sync:

sound.pause();sound['_startOffset'] = milliStartPoint;sound.play(0);
