- Create a sound with as3sfxr (https://www.superflashbros.net/as3sfxr/)
- Copy settings string (Just use Ctrl+C on the as3fxr page) and save it as a JavaScript array
- String looks something like this: "0,,0.1812,,0.1349,0.4524,,0.2365,,,,,,0.0819,,,,,1,,,,,0.5"
- Should be passed as JavaScript array like this: [0,,0.1812,,0.1349,0.4524,,0.2365,,,,,,0.0819,,,,,1,,,,,0.5]
- Play sound in JS using the following code:
// asfxr string gets passed into jsfxr as array
var soundURL = jsfxr([0,,0.1812,,0.1349,0.4524,,0.2365,,,,,,0.0819,,,,,1,,,,,0.5]);
var player = new Audio();
player.src = soundURL;
player.play();
