mp3

I have this mp3 3531Kb in my site.
when I only place in library swf I increase considerably and being main.swf sufficiently weighed.
I can make of another form?

i have this

import flash.media.Sound;
import flash.media.SoundChannel;

var soundOn:Boolean=true;
var myMusic:TitleMusic = new TitleMusic();
var myChannel:SoundChannel=myMusic.play(0,1000);
var myTransform:SoundTransform;

mySoundButton.addEventListener(MouseEvent.CLICK,toggleSound);
mySoundButton.buttonMode=true;
mySoundButton.mouseChildren=false;


function toggleSound(e:MouseEvent) {
    if (soundOn) {
       
        myTransform = new SoundTransform();
        myTransform.volume=0;
        myChannel.soundTransform=myTransform;
        soundOn=false;
        mySoundButton.myButtonText.text="ON";
    } else {
      
        myTransform = new SoundTransform();
        myTransform.volume=1;
        myChannel.soundTransform=myTransform;
        soundOn=true;
        mySoundButton.myButtonText.text="OFF";
    }

}
