Unable to Switch Audio Sync Settings

It may be that some things will be too hard to do in Javascript compared to AS3 playing in a native code plugin. In the case of Stream sync though you can code your own solution for playback. Look at this code as an example way of making a 500 frame animation keep up with real time Event audio:

var fps = 24;

var starttime = createjs.Ticker.getTime();

createjs.Ticker.setFPS(fps);

createjs.Ticker.addEventListener("tick", movealong);

self = this;

var firstframe = 0;

var lastframe = 500;

function movealong() {

  var now = createjs.Ticker.getTime();

  var f = Math.min(lastframe,Math.floor((now - starttime) / 1000 * fps + firstframe));

  self.gotoAndStop(f);

}

Hi,

Is it possible for you to share the AS3 fla where the Sync type is disabled for us to investigate?

You can us any file sharing utility like Drop Box to share the fla.

Thanks!

Hi,

As Kristofer pointed out, if you are in HTML5 Canvas document then these sound options (Effect type and Sync type) are disabled. The target platform(HTML5 Canvas) doesnt support these functionalies and hence they are disabled.

You will get the following message if you try to paste a layer with such sound properties

* Effect type of Sound cannot be imported in HTML5 Canvas document.

* Sync type is not supported in HTML5 Canvas document, and has been converted to Event.

If you create a ActionScript 3.0 document then these options are available for you to manipulate where the target platform(Flash) has a support the same.

Thanks!

Thank you so much Kristofer. I seriously spent the last 20 minutes trying different audio formats and the whole nine, then finally came up with the right google search word combination to find the solution. I knew it was going to be some kind of simple fork in the road issue. Action Script 3 doc, and I'm off and running. Much appreciated.

The first the thing a person should always do when they encounter a problem is restart their computer. No worries, I did that.

I tried converting the file to OGG and WAV to see if it would work better. Apparently Flash Professional handles WAV fine, allowing me to switch between Stream and Event audio sync settings. That's kind of strange, because WAV files are so huge and aren't practical when developing a game or something like that.

Thankfully, I'm just using Flash Professional to export a video, so I don't care about file size, but it's a disturbing bug.

If anyone knows why I was unable to switch to Stream audio sync settings with MP3 files, please speak up.
