Sound fading Query

[font=Lucida Console]i’m trying to get mp3 sounds to fade in and out as the user switches from scene to scene. [/font]
[font=Lucida Console][/font]
[font=Lucida Console]basically something like this:[/font]
[font=Lucida Console][/font]
[font=Lucida Console]<Scene1:>[/font]
[font=Lucida Console][/font]
on (release) {
gotoAndPlay(“Scene 2”, 1);
— fade out mp3 for scene 1 —
}

<Scene 2:>

onClipEvent (load) {

— fade in mp3 sound for sene 2 —
}

a thought anyone?
