SoundChannel position

Why isn't the end position of a sound channel the same as the length of a sound?
        public function play():void
            soundChannel = sound.play();
            soundChannel.addEventListener(Event.SOUND_COMPLETE, onSoundComplete);
        private function onSoundComplete(e:Event):void
            var endPosition:Number = soundChannel.position;
            var length:Number = sound.length;
If you test the previous code you will see that the position of the soundChannel when SOUND_COMPLETE is dispatched is different then the length of the sound.
Why isn't the soundChannel play all the sound? Why does it stops earlier? and how can I find the end position of the soundChannel without playing and listening to the SOUND_COMPLETE event?

imnikey,
I see no one has answered your question. I don't have an answer either, but I'm experiencing similar problems with the SoundChannel position. The problem with tracking the sound object's position through its sound channel gets worse when there is more than one Flash movieclip open in a different browser window. Opening a Flash audio player seems to work fine if it is the only Flash movieclip open on my desktop. After I open another Flash object in a separate window, the audio player fails to properly track the SoundChannel position, and fails to correctly fire the SoundComplete event.
Anyone else experiencing these problems? Has anyone been able to find a reliable method for tracking the sound channel position with more than one Flash movieclip open on the desktop? Is this a known issue or bug with the Sound API for Flash Player 10? We could really use some answers.

[AS3.0]SoundChannel.position≠Sound.length

別の掲示板の引用で恐縮ですが、まさにこの問題に直面しています。
http://www.flash-jp.com/modules/newbb/viewtopic.php?topic_id=7819&forum=8&post_id=38874#f orumpost38874
上記サイトで書かれていますが、
「 Firefox 2.0.0.14 & Internet Explorer 7.0/Windows Vistaで確認したところ、SoundChannel.positionプロパティの値がSound.lengthの値に達しないという問題が生じました。」
の問題に対する、解決策、回避策などはございませんでしょうか。
AS3.0＋Vistaの環境では、mp3の再生に合わせてバーを伸縮させるスライダーようなものは作れない、なんてことはないと思うのですが・・・
再生終了時のpositionの値がlengthの値と同じにならなくても、その終了した時の値が、再生前に分かれば問題ないのだと思うのですが、そのようなことは無理でしょうか。
その他、何か情報がありましたら、ぜひよろしくお願いいたします。

Thanks Andrei.

I managed to get it to move each second though with this:
var myTimer:Timer = new Timer(1000);
myTimer.addEventListener(TimerEvent.TIMER, runTimer);
myTimer.start();
function runTimer(event:TimerEvent):void {
trace("Hello");
progreso.value = progreso.value+1;

SoundChannel.position inaccuracies within SampleDataEvent.SAMPLE_DATA

The application generates sound dynamically by handling SampleDataEvent. It needs to determine exactly what part of the sound was actually playing when a click was made.
Unfortunately, the latency calculation is slightly off because SoundChannel.position seems to be returning values that are +- 20 milliseconds off. The attached class demonstrates the issue by using a timer to occasionally check the position against the current time, displaying the difference between the two, along with the range of differences over time. The timer fires as often as it can so different ranges can be seen by using different movie frame rates.
I'm not sure why this is, but I'm guessing it's something to do with the fact that the sound buffering is happening in a separate thread. Perhaps this thread only periodically updates the main thread about its position?
Is there any more accurate way to calculate latency? Or maybe some way to know just how much the position value with be off at any given time?

SoundChannel.position won't reset

I'm trying to play an audio that goes along with the text on the screen. As the audio plays, a timer event handler checks the SoundChannel.position to see determine what text should be highlighted. In my application I have a few audios that play in succession. When one ends, the SoudComplete event is fired and I start playing the next audio. I create a new sound object and reset the timer, but for some reason, the SoundChannel.Postion is off. Here is my code:
private function soundComplete(evt:Event):void
//unHighlightSegment(this.curSegment_int);
//timer.removeEventListener(TimerEvent.TIMER, highlightNext);
//timer.stop();
oSoundChannel.removeEventListener(Event.SOUND_COMPLETE, soundComplete);
/*oSoundChannel = null;
oSound = null;*/
//timer.reset();
if(this.toggleFull_bl && (curSegment_int+1 < this.dialogueText_ary.length))
if(this.normal)
playAllNormal(curSegment_int+1);
else
playAllSlow(curSegment_int+1);
return;
dialoguePlaying = false;
firstPlay = true;
isPaused = false;
stopPlaying();
playDialogue_btn.gotoAndStop("playUp");
//plays the entire audio
private function playAllNormal(seg:uint):void
//trace(audiosToPlay_ary[curDialogue_uint] + "_nml.mp3");
//soundEnd = true;
timer.stop();
timer.reset();
timer.removeEventListener(TimerEvent.TIMER, stopVocalPlayback);
timer.removeEventListener(TimerEvent.TIMER, highlightNext);
trace("playAllNormal", seg);
try
trace("stop audio");
oSoundChannel.stop();
catch(e:Error)
trace("Sound Channel object not yet created");
var temp:int = dialogInfo.Segment[seg].Dialog;
trace(String("CurrentDialog"), temp);
oSound = new Sound(new URLRequest(audiosToPlay_ary[temp] + "_nml.mp3")); //Create a new sound
oSoundChannel = oSound.play(uint(audioTimes[temp].Time[dialogInfo.Segment[seg].Seg])); //Play the sound and assign this to oSoundChannel
trace(audiosToPlay_ary[temp] + "_nml.mp3", audioTimes[temp].Time[dialogInfo.Segment[seg].Seg]);
oSoundChannel.addEventListener(Event.SOUND_COMPLETE, soundComplete);
oSoundTransform.volume = volumeLevel;
oSoundChannel.soundTransform = oSoundTransform;
trace("Sound position just after play", oSoundChannel.position); //oSoundChannel.position should be close to zero here.
timer.addEventListener(TimerEvent.TIMER, highlightNext);      //add the timer event to check the soundchannel position
timer.start();
private function highlightNext(evt:TimerEvent):void
var len:uint;
len = this.dialogueText_ary.length;
if(normal)
if(curSegment_int+1 < len)
if(oSoundChannel.position >= uint(audioTimes[dialogInfo.Segment[curSegment_int].Dialog].Time[dialogInfo.Segment[curSeg ment_int].Seg]) && oSoundChannel.position < uint(audioTimes[dialogInfo.Segment[curSegment_int].Dialog].Time[dialogInfo.Segment[curSeg ment_int].Seg+1]))
highlightSegment(curSegment_int);
var a:int = 1;
else //if the position is not within range, highlight the next segment and increment the curSement counter
unHighlightSegment(curSegment_int);
curSegment_int++;
trace("highlightNext", curSegment_int, oSoundChannel.position);
else if(curSegment_int+1 == len)
highlightSegment(curSegment_int);
else
if(curSegment_int+1 < len)
if(oSoundChannel.position >= uint(audioTimes[dialogInfo.Segment[curSegment_int].Dialog].TimeSlw[dialogInfo.Segment[cur Segment_int].Seg]) && oSoundChannel.position < uint(audioTimes[dialogInfo.Segment[curSegment_int].Dialog].TimeSlw[dialogInfo.Segment[cur Segment_int].Seg+1]))
highlightSegment(curSegment_int);
else
unHighlightSegment(curSegment_int);
curSegment_int++;
else if(curSegment_int+1 == len)
highlightSegment(curSegment_int);

Any ideas on why the position is not close to zero just after I begin playing?

Somewhere between the sound ending and the firing of the soundComplete event, the timer still keeps counting and firing the timer event. Any suggestions on how to stop the timer? I already call Timer.stop() and Timer.RemoveEventListener when the sound complete fires, but the timer still has time to fire several times before I can stop it in the SoundComplete event handler.

Trouble Understanding variables

I am committed to learning A3, but HOLY CRAP!! I have never
been a programmer, just a lowly designer. Apparently a pretty dumb
designer! :)
I can breeze through this in AS2 with no problem, but AS3 is
killin' me! I am trying to create a music player that will embed in
a web page, it will be XML driven and the XML will be populated via
a database and generated by PHP. I am using a listbox component to
display the playlist (from the XMLfile). I have figured out how to
start playing the first mp3 on the list.
Now when the user click a different button, I can get that
song to play also, but I ended up created a second sound object, so
the two play at the same time. Not good. I have tried and tried to
access the object that is playing the first sound so I can stop it
and load a new sound into it - I am about to pull my hair out!
I seem to missing a basic understanding of how to access this
object and change the variable value so I can play a new song. Any
help would be GREATLY appreciated!!

Vern,

use outside

declared OUTSIDE

Yes.

Is that correct?
Close. In fact, if you're coding in the main timeline,
you're so close,
you could arguably define it in those terms and be fine.
Variables (and
functions) are available to the scope in which they're
declared. If you
declare a variable in the main timeline, then that variable
is available in
that frame and any subsequent frame of that timeline.
Depending on the
circumstances of your FLA, the main timeline may indeed feel
like
"everywhere," to the point where the variable could be said
to be used
"anywhere" -- but it's really not much different from the
restriction a
variable feels when declared inside a function; it's just
that the whole
movie takes place inside that "function"/FLA/SWF.

up some

Yes. That way, any number of functions can use those
variables. But
keep in mind, all you really need are variables that point to
your instances
of Sound, SoundChannel, and MovieClip. Then use those
variables to
reference the necessary properties of those classes. (In
other words, no
need to make a mySound variable *and* a mySoundLength
variable: the mySound
variable suffices, because it leads to the Sound.length
property as simply
as mySound.length.)

the Timer

It's just another tool in the toolbox. :) Timer is the
recommended new
version of setInterval() and setTimeout() combined.
> I am so used to _root.movieClip.variable=foo; (I mean
the easy

good, I like

I like change in my pocket! ;) The thing about an expression
like
_root.movieClip.variable is that you could often just
reference the variable
anyway, without the need for the "_root" reference. AS3 has
root (no
underscore), which behaves in many ways like _root, but dig
into that a bit
... you'll find some important differences.

You could do a set length, but it's much more flexible if
you use the
width of some other object, like a track or some other movie
clip. If you
go with the width of some object, you can *change* the width
of that object
and the code still works.

actual audio

To derive volume, you'll take the position of the draggable
knob along
its track and divide that by the width of the track. Assume
you have a
ridiculously long volume track, 500px. The volume knob has
been dragged
halfway across, to 250px. 250 / 500 is 0.5, which is the AS3
way of
specifying 50% volume. Now imagine the track is 50px wide.
The knob has
been dragged all the way across (to 50px). 50 / 50 is 1,
which is 100%
volume. And so on.

to try and add

working, or is

Ehh, for something like this -- especially if you're
teaching yourself
and involved in a learning experience -- I'd say it doesn't
matter one way
or the other. Take small steps and master each step. Sooner
or later, what
you're doing will "click" for you, and after that, you'll
find that you can
add or remove features as you please.

Function to change mp3 and frame (video)

I am currently working on a music site that has a custom built mp3 player, where the action script calls to an external xml. It works beautifully. It is all on one frame.... in the background of the music player is edited video that I manipulate in final cut. I have next and pre buttons that call the xml. What I am trying to do is change the video when the song is changed. Im not sure if I call a fuction to the button next frame + or - 1 or if I can call the video to the xml. I am a graphic designer learning code and am not sure how to tackle this. This site is my senior project..Please help!!!

remove the video code from that movieclip, assign that movieclip an instance name (eg, flv) and use:
<?xml version="1.0" encoding="ISO-8859-1"?>

<song>
<title>Namasta</title>

Seek bar for music

Hi!
I know flash has seek bar component for flv videos but I'm
streaming music from net. I have a code for loading entire song but
is it possible to add a seek bar to show what part of song is
playing

Yes, if you just want to track the progress of the sound
file's playing, its pretty simple. You'll need a couple of
variables, one to hold the value of the sound file's duration. And
another to define the width of the seek bar object.
In your download complete function give the duration variable
the value of the sound's duration property. Then assign an
enterframe function to update the seek bar. Just take the
soundChannel.position property value and divide it by the sound
file's duration property value. This will give you a ratio of the
current position relative to the total time. Then multiply that
value by the total width of the seek bar. Position the marker at
that point on the seek bar.

Help needed to load different xml playlists by clicking button

Hi there,
I have a series of buttons, when i double click a button i want to load a new xml file
I have some functioning code, but when i click on more than one button per run of the application, it will only use the first xml that was clicked / loaded.
Does anyone have any suggestions I would be really grateful
Thanks!

You should try to limit the code you post to what is relevant to the problem... it is hard to track things down, especially when your code is not formatted properly with indentations.
I didn't search farther than finding that you remove the event listener for the URLLoader...
XMLLoader.removeEventListener(Event.COMPLETE, processXML);
so if you remove it after you load the first file and do not restore one for it, then chances are you don't "processXML" any more than the first file you load

Will the FLVPlayback component play MP3's without FMS?

Will the FLVPlayback Component (version 2.5.0.15) play an MP3 file without it having to be streamed through a Flash Media Server? All I'm looking for is to place a player into my Flash that plays an MP3 file that's in the same directory as the SWF.
Here's my code... it's pretty simple:
import fl.video.FLVPlayback;
var myMusic:FLVPlayback = new FLVPlayback();
myMusic.source = "mySong.mp3";
myMusic.skin = "SkinOverPlayMute.swf";
myMusic.skinBackgroundColor = 0xCCCCCC;
addChild(myMusic);

So the answer is no, correct? FLVPlayback will not handle MP3 files?
My new script, in case anyone is interested:
import flash.media.Sound;
import flash.net.URLRequest;
var songTitle:String = "Shake Your Rump"
var fileName:String = "shakeYourRump.mp3"
var myMusic:Sound = new Sound(new URLRequest(fileName));
var soundChannel:SoundChannel;
var isPlaying:Boolean = false;
var currentPosition:Number = 0;
btn_Rewind.addEventListener(MouseEvent.CLICK,rewindMusic);
btn_Play.addEventListener(MouseEvent.CLICK,playMusic);
btn_Pause.addEventListener(MouseEvent.CLICK,pauseMusic);
txt_Status.text = 'Click play to hear "' + songTitle + '"';
function rewindMusic(myEvent:Event): void {
currentPosition = 0;
txt_Status.text = 'Rewinding "' + songTitle + '" Click play to restart.';
if (isPlaying) {
soundChannel.stop();
soundChannel = myMusic.play(currentPosition);
txt_Status.text = 'Playing "' + songTitle + '"';
function playMusic(myEvent:Event): void {
if (!isPlaying) {
soundChannel = myMusic.play(currentPosition);
isPlaying = true;
txt_Status.text = 'Playing "' + songTitle + '"';
function pauseMusic(myEvent:Event):void {
if (isPlaying) {
currentPosition = soundChannel.position;
soundChannel.stop();
isPlaying = false;
txt_Status.text = '"' + songTitle + '" is paused. Click play to resume.';
stop();

Sound.Play() start time not consistent

When I play an audio and give it a start time, eg sound.play(3366), it doesn't always play at that position. I'm working on an application that is dependent on the soundChannel position, but after I start the sound, it sometimes doesn't start at the exact position I tell it too. Sometimes the position starts at something like 3365.986394557823. I found a workaround of just using Math.ceil, but I still wonder why the position isn't true to the start parameter. Anyone know why that is?

yes?? The song is Paper Walls by Yellowcard. You can listen to it yourself, but to explain it they play this intro of the song (which I dislike) and then it pauses for a couple of seconds and then the actual song starts. listen to the song here: http://www.youtube.com/watch?v=GjENnmGf-Jc

Tracking sound progress

Hello everyone. I've managed to build this mp3player but need to have the horontal component advance as the sound progreses. Any ideas?

The first step is to make sure that you are running the latest software.
You should have version 1.2 for the iPod and 6.05 for iTunes.
Do you have the correct software?

I have another slider component on the movie with instance name PROGRESO
I would like for PROGRESOnto indicate (update) the sounds progress as it plays and be able to scrub through the sound.
Any idea how I can achieve this? Thanks for any help

Thanks Andrei.
But I really dont understand. You see, I am not too good (actually pretty bad) with Ationscript 3.

I managed to get it to move each second though with this:
var myTimer:Timer = new Timer(1000);
myTimer.addEventListener(TimerEvent.TIMER, runTimer);
myTimer.start();
function runTimer(event:TimerEvent):void {
trace("Hello");
progreso.value = progreso.value+1;

Serious Help! Handling Sound Position And Speed!

Take a look at this: https://sites.google.com/site/pardeepgames/Untitled-1.swf. It may take some time to load, sound is 42 seconds, see the second text field for time buffering.
I recommend reading the Source Code below first.
Now as you can see the pitch and speed functions are working perfectly, but the problem is that when you move the slider, the songTime text field dosen't work correctly. When you raise the pitch the songTime should just speed up the counting not change it's position, same when you lower the pitch, it should just slow down the counting not change it's position. Well that isn't working for me. The Source Code is there for you below and all the information you need is in the comments in the code. Please help me out. Oh and I recommend focusing on the songTime text field and then moving the slider.
Source Code:
Name of the slider: "slider".
Name of the first text field: "songTime".
Name of the second text field: "songTotalTime".

your options are to keep working on this yourself or hire someone to help you. if you can narrow down the problem's location and post the problematic code you could still get free help.

AS3 play and pause timeline as well as soundchannels

I am trying to make global playback control buttons to play & pause the timeline as well as the sound channels. I have managed to get the buttons to function correctly with controlling the timeline but I need them to also work with the soundchannels too.
Here is the code I created for the buttons:
btnStop.visible = true;
btnPlay.visible = false;
var movieclip:MovieClip;
function stopMovieClip(mc:MovieClip):void{
mc.stop();
for (var i:int = 0; i < mc.numChildren; i++)
var mcChild = mc.getChildAt(i);
if (mcChild is MovieClip) stopMovieClip(mcChild);
btnPlay.visible = true;
btnStop.visible = false;
function playMovieClip(mcPlaying:MovieClip):void{
mcPlaying.play();
for (var j:int = 0; j < mcPlaying.numChildren; j++)
var mcPlay = mcPlaying.getChildAt(j);
if (mcPlay is MovieClip) playMovieClip(mcPlay);
btnStop.visible = true;
btnPlay.visible = false;
btnStop.addEventListener(MouseEvent.CLICK, stopAll);
function stopAll(event:MouseEvent):void
stopMovieClip(con);
btnPlay.addEventListener(MouseEvent.CLICK, PlayMC);
function PlayMC(event:MouseEvent):void
playMovieClip(con);
And the code for the soundchannels:
import flash.media.SoundChannel;
var strokeVOSound:strokeVO = new strokeVO();
var strokeVOChannel:SoundChannel = new SoundChannel();
var bleedVOSound:bleedVO = new bleedVO();
var bleedVOChannel:SoundChannel = new SoundChannel();
yellow_mc.visible=false;
blue_mc.visible=false;
strokebtn_mc.addEventListener(MouseEvent.CLICK, displayStroke);
strokebtn_mc.buttonMode = true;
function displayStroke(e:MouseEvent):void {
trace ('Clicked')
yellow_mc.visible=true;
blue_mc.visible=false;
bleedVOChannel.stop();
strokeVOChannel = strokeVOSound.play();
bleedbtn_mc.addEventListener(MouseEvent.CLICK, displaybleed);
bleedbtn_mc.buttonMode = true;
function displaybleed(e:MouseEvent):void {
yellow_mc.visible=false;
blue_mc.visible=true;
trace ('Clicked')
strokeVOChannel.stop();
bleedVOChannel = bleedVOSound.play();
The soundchannels are triggered by a movieclip which acts as a button.
Any help would be much appreciated.
Thanks

For the two soundchannel sounds you have, you will need to keep track if and which one is playing so that you can use some logic to stop the sound right after you mark where the sound was (position) so that you can resume playing it again when the play button is selected.
So if the stroke sound is started, you could assign a boolean variable named something like 'strokeplaying' to be true (setting the other sounds similar boolean false). Then, in your pause function you would test to see if strokeplaying is true and if it is, store the position property and stop the channel playing.
When play is selected, similarly, you test if that sound is true and if so you restart it using the position value you stored as the starting point. You do the same for the other sound... remembering that it is possible neither is playing when pause it clicked.
