Position of noisy mesh relative to hero for Audio

[JackFalcon]

Hello,

      Evaluating Web Audio API, for 3D sound, mixed HowlerJS with BJS without realizing: Oh, Babylon.Sound ... ? Whylookathat, lots of sound! : )

      Thanks to answer below, with links. I will head that way.

       Related question is  around WebAudio API AudioContext and ->

                     compressors, oscillators, reverb, etc. with JS! +1. 

                            That should all be available through the AudioContext in Web Audio API... if there is an example. If not. I'll dig down, figure it out, and put it here.... : )

       Applying 3D Sound with BABYLON.Sound. : )

Cheers.

This does not answer your question, but I don't know if you have seen sound.attachToMesh(), which accomplishes what you are trying to do position-wise. Maybe you can copy that?

Nice! I hadn't run across that just yet. I'll look into it... thanks.

Thank you Mr. brianzinn,

Look 3D sound... : ) cool.  

Remembers two-step process: 1) open file babylon_v3.0_max.js 2) read... sound!

Reading through .max.js is really nice...

Moves to corner... I'll  dig over near that... world conversion to local, matrix transformation mathmatification...real quick

before checking out BABYLON.Sound = Sound; thanks...

Solution: Babylon.Sound, is pretty great. Even more so after comparison. Sound interface is nicer than others.

Here is solution to noisy mesh in relation to hero:

var assetsManager = new BABYLON.AssetsManager(scene);

var binaryTask3 = assetsManager.addBinaryFileTask("snd3task", "../audio/CC/zap1.wav");
binaryTask3.onSuccess = function (task) {
    soundObj3 = new BABYLON.Sound("zap1", task.data, scene, null, { loop: true, volume: 2.5, 
        spatialSound: true, 
        distanceModel: "exponential", //"inverse"
        maxDistance: 10, //distance to 0 volume.
        rolloffFactor: 2 });
}

assetsManager.load();

soundObj3.setPosition(noisyMesh1.position);

This simplification was also nice(via brianzinn):

soundObj3.attachToMesh(noisyMesh1);
