播放与停止
砸在舞台添加一个小按钮，然后在第1帧写上如下代码：
import flash.net.URLRequest;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.events.MouseEvent;
var url:URLRequest = new URLRequest("kate havnevik - solo.mp3");
var sound:Sound = new Sound();
sound.load(url);
var position:Number = 0;
var channel:SoundChannel = new SoundChannel();
btn.label = "播放";
btn.addEventListener(MouseEvent.CLICK,PS);
function PS(e:MouseEvent):void
{
if(btn.label == "播放")
{
channel = sound.play(position);
btn.label = "停止";
}
else
{
channel.stop();
position = channel.position;
btn.label = "播放";
}
}
播放与暂停
与播放与停止类似，相差不大。
import flash.media.Sound;
import flash.net.URLRequest;
import flash.media.SoundChannel;
import flash.events.MouseEvent;
var sound:Sound = new Sound();
sound.load(new URLRequest("kate havnevik - solo.mp3"));
var p:Number = 0;
var channel:SoundChannel = new SoundChannel();
btn.label = "播放";
btn.addEventListener(MouseEvent.CLICK,PS);
function PS(e:MouseEvent):void
{
if(btn.label == "播放")
{
channel = sound.play(p);
btn.label = "暂停";
}
else
{
p = channel.position;
channel.stop();
btn.label = "播放";
}
}
加载进度条
import flash.display.Sprite;
import flash.net.URLRequest;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.events.ProgressEvent;
import flash.events.Event;
//进度条
var bar:Sprite = new Sprite();
bar.graphics.beginFill(0x123456);
bar.graphics.drawRect(0,0,350,20);
bar.graphics.endFill();
addChild(bar);
bar.x = 75;
bar.y = 350;
bar.scaleX = 0;
var bar2:Sprite = new Sprite();
bar2.graphics.beginFill(0x876543);
bar2.graphics.drawRect(0,0,350,20);
bar2.graphics.endFill(); addChild(bar2);
bar2.x = 75;
bar2.y = 350;
bar2.scaleX = 0;
var url:URLRequest = new URLRequest("1.mp3");
var sound:Sound = new Sound();
sound.load(url);
var channel:SoundChannel = new SoundChannel();
sound.addEventListener(ProgressEvent.PROGRESS,Progress);
sound.addEventListener(Event.COMPLETE,addSound);
addEventListener(Event.ENTER_FRAME,changeV);
function Progress(e:ProgressEvent):void
{
bar.scaleX = e.bytesLoaded/e.bytesTotal;
trace(e.bytesLoaded/e.bytesTotal)
}
function addSound(e:Event):void
{
channel = sound.play();
}
function changeV(e:Event):void
{
bar2.scaleX = channel.position/sound.length ;
trace(channel.position/sound.length);
}
控制声音和声像
import flash.media.Sound;
import flash.media.SoundTransform;
import flash.media.SoundChannel;
import flash.net.URLRequest;
import flash.events.Event;
var snd:Sound = new Sound(new URLRequest("1.mp3"));
var trans:SoundTransform = new SoundTransform(0.6,-1);
var channel:SoundChannel = snd.play(0,1,trans);
var hd:Number = 0;
addEventListener(Event.ENTER_FRAME,aa)
function aa(e:Event):void
{
hd+=0.1;
trans = new SoundTransform(1,Math.sin(hd));
channel.soundTransform = trans;
trace(hd);
}
修改MP3的声音
import flash.media.Sound;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.SampleDataEvent;
import flash.utils.ByteArray;
var mysound:Sound = new Sound();
var sourceSnd:Sound = new Sound();
var url:URLRequest =new URLRequest("1.mp3");
sourceSnd.load(url);
sourceSnd.addEventListener(Event.COMPLETE,loaded);
function loaded(e:Event):void
{
mysound.addEventListener(SampleDataEvent.SAMPLE_DATA,processSound);
mysound.play();
}
function processSound(e:SampleDataEvent):void
{
var bytes:ByteArray = new ByteArray();
sourceSnd.extract(bytes,8192);
e.data.writeBytes(upOctve(bytes));
}
function upOctve(bytes:ByteArray):ByteArray
{
var returnBytes:ByteArray = new ByteArray();
bytes.position = 0;
while(bytes.bytesAvailable > 0)
{
returnBytes.writeFloat(bytes.readFloat());
returnBytes.writeFloat(bytes.readFloat());
if (bytes.bytesAvailable > 0)
{
bytes.position += 8;
}
}
return returnBytes;
}
