获取声音的总时间和当前时间？ [英] Get sound's total time and current time?

问题描述

我有一个球员在闪光的ActionScript 3。我需要的声音文件的声音文件和当前时间的总时间。 我的code：

I have a player in flash ActionScript 3. I need to take a the total time of the sound file and current time of the sound file. My code:

function onPlayProgress(evt:Event):void {
            var sndLength:int = Math.ceil(snd.length /(snd.bytesLoaded / snd.bytesTotal));
            var seekbar = 100 * (channel.position / sndLength);
            playBar.seekbar.x = seekbar*5.8;
            var _totalTime:Number = (((snd.length /(snd.bytesLoaded / snd.bytesTotal))*0.001/60));

什么是当前的时间？

What is current time?

推荐答案

我不是你所提供的code样品试图传达完全清楚，但如果你想获得声音的当前位置正在播放，你会做这样的事情：

I'm not entirely clear on what the code sample you provided is trying to communicate, but if you want to get the current position of a sound that's playing you would do something like this:

protected var sound:Sound; 
protected var soundChannel:SoundChannel;

protected function loadSound():void
{
    sound = new Sound(new URLRequest("path_to_sound.mp3"));
    sound.addEventListener(Event.COMPLETE, onSoundLoadComplete);
{

protected function onSoundLoadComplete(e:Event):void
{
    sound.removeEventListener(Event.COMPLETE, onSoundLoadComplete);
    soundChannel = sound.play();
    addEventListener(Event.ENTER_FRAME, onEnterFrame);
}

//Calculuate the sound time
protected function onEnterFrame(e:Event):void
{
    var minutes:uint = Math.floor(soundChannel.position / 1000 / 60);
    var seconds:uint = Math.floor(soundChannel.position / 1000) % 60;
    trace('position: ' + minutes + ':' + seconds);        
};
