music loop fade out by button between scenes

Hi

I have a infinite music loop and I am trying to have btn_start trigger a fade out on the music along with its original gotoAndPlay.

I have two scenes, "opening" and "animation". btn_start and the following code are in the "opening" scene.

the fade out will play along with the first couple seconds of "animation" since the gotoAndPlay connects to frame 1 of "animation"

Can this be done? Please show me some lights of how to proceed this.

stop();

import flash.net.URLRequest;
import flash.media.Sound;

var url:URLRequest = new URLRequest("subtle.mp3");
var snd:Sound = new Sound(url);
snd.play(0, 17);

btn_start.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void {

gotoAndPlay(1, "animation");

}

thanks!!

Correct answer kglad

you can use:


stop();

import flash.net.URLRequest;
import flash.media.Sound;

var fadeRate:Number = .01;  // number between 0 and 1.  the closer to 1, the faster the fade


var url:URLRequest = new URLRequest("subtle.mp3");
var snd:Sound = new Sound(url);
var sc:SoundChannel=snd.play(0, 17);

btn_start.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void {
this.addEventListener(Event.ENTER_FRAME,fadesoundF);
gotoAndPlay(1, "animation");

}

function fadesoundF(e:Event):void{

var st:SoundTransform=sc.soundTransform;

st.volume-=fadeRate;

if(st.volume<=0){

this.removeEventListener(Event.ENTER_FRAME,fadesoundF);

}

sc.soundTransform=st;

}
