Trying to read high millisecond cue point time

Report · Oct 11, 2013

Hi,

I'm learning AC3. I'm using the script in an AS file to read cue points in milliseconds. These cue points are set by code in a frame script in the main timeline like this:

// Create an instance of SoundSync
var ss:SoundSync = new SoundSync();

// Use instance to add cue points to sound file
//puts a cuePoint in the soundtrack at the millisecond location indicated after the comma
ss.addCuePoint("someString1",01969);

Here is the AS file script that reads these cue points:

package net.quip.sound
{
import flash.events.Event;
import flash.events.TimerEvent;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.media.SoundLoaderContext;
import flash.media.SoundTransform;
import flash.net.URLRequest;
import flash.utils.Timer;
public class SoundSync extends Sound
{
// PROPERTIES
private var _cuePoints:Array;
private var _currentCuePoint:uint;
private var _timer:Timer;
private var _timerInterval:uint;
private var _startTime:Number;
private var _loops:uint;
private var _soundChannel:SoundChannel;
// CONSTRUCTOR
public function SoundSync(stream:URLRequest = null, context:SoundLoaderContext = null) {
super(stream, context);
init();
}
// METHODS
// init
private function init():void {
_cuePoints = new Array();
_currentCuePoint = 0;
_timerInterval = 50;
_startTime = 0.0;
}

// Add Cue Point
public function addCuePoint(cuePointName:String, cuePointTime:uint):void {
_cuePoints.push(new CuePointEvent(CuePointEvent.CUE_POINT, cuePointName, cuePointTime));
_cuePoints.sortOn("time", Array.NUMERIC);
}
// Get Cue Point
public function getCuePoint(nameOrTime:Object):Object {
var counter:uint = 0;
while (counter < _cuePoints.length) {
if (typeof(nameOrTime) == "string") {
if (_cuePoints[counter].name == nameOrTime) {
return _cuePoints[counter];
}
} else if (typeof(nameOrTime) == "number") {
if (_cuePoints[counter].time == nameOrTime) {
return _cuePoints[counter];
}
}
counter++;
}
return null;
}
// Get Current Cue Point Index
private function getCurrentCuePointIndex(cuePoint:CuePointEvent):uint {
var counter:uint = 0;
while (counter < _cuePoints.length) {
if (_cuePoints[counter].name == cuePoint.name) {
return counter;
}
counter++;
}
return null;
}
// Get Next Cue Point Index
private function getNextCuePointIndex(milliseconds:Number):uint {
if (isNaN(milliseconds)) {
milliseconds = 0;
}
var counter:uint = 0;
while (counter < _cuePoints.length) {
if (_cuePoints[counter].time >= milliseconds) {
return counter;
}
counter++;
}
return null;
}
...

Here's my problem: When I set a cue point that is a minute or more (in milliseconds) as in:

ss.addCuePoint("someString1", 107055); //this isn't processed by the AS script

...the cue points aren't read (nothing happens).

Probably it's because I need to allow for that possibility in that AS file above. (It's not my script so I don't know how to adjust it. It's from a great tutorial by David Stiller on the Adobe site: http://www.adobe.com/devnet/actionscript/articles/cue_points_audio.html).

Can anyone tell me how to adjust the AS script so I can read a cue point that goes beyond 5 places?

Thanks much!

Human error. I was not understaning millisecond conversion. SoundSync AS code is is good. I need the work.
