Sound Fade Out

Intoduction

I had this problem. I wanted to have a looping sound playing along with a movie and fade out as the movie reached its end.
Flash has a fade out effect in the Edit Envelope panel. There you can force a certain loop to fade out.
This didn't suit my case because I didn't know the exact loop to fade out since a movie, loaded with tweens and heavy graphics, doesn't last the same in every computer.
There's also the Stream option, but it usually turns the music to sound terrible.
Even worse, combined with ActionScript, can turn the movie into a disaster since it skips frames.
So I found a solution in creating a FadeOut movie clip that, attached to the movie, can fade any music out no matter the computer it is played in.
