I made this object to take care of this autofade. You init it with the sound
mc and update interval i ms.
You can then call it with (target volume, length of fade time and delay)
Hope you find it usefull:
class SoundAuto extends Sound{
private var intervalId:Number
private var
In my movie, I have a jingle, that is loaded by this code:
code:---
---track = new Sound();
track.loadSound(everybody.mp3, true);
track.setVolume(0);
vol = 0;
fade = setInterval(fadeIn, 100);
function fadeIn() {
vol += 1;
Hi,
Here is a Sound prototype I often use. You can also easily set it as a
function in a sound class:
Sound.prototype.volumeTo=function(nTarget:Number,step:Number,post_func:Funct
ion){
var a=nTarget - this.getVolume();
var v=this.getVolume();
var dir=a/Math.abs(a);
If you want to keep things simple, and the volume fade doesn't need to
be linear, couldn't you just run a soundUpdate function and keep track
of the volume in a variable. something like this:
var volume = 0;
var destVolume = 100;
setInterval(soundUpdate, 100);
function soundUpdate() {
I've found that linear adjustments prove to sound highly inaccurate -
or strange. You'll notice no difference, and then the change will be
quite abrupt. So be careful with these kinds of things - linear is
probably not the best way to go.

so then the code here would work since it's not linear.
but i'm not sure what you mean by linear adjustments prove to sound
highly inaccurate? in this case i don't think it matters anyway since
it's just a small change of volume and he's probably not coding some
online dj mixing software. or
I guess I'm saying that any audio fading up or down should probably not be
done linearly ever - while mathematically accurate, to the human ear it
doesn't sound right. You'll notice no change and then zm... a really
quick fade down... when what you wanted was something even if you know
what I
Basically yes :)
Flash has no notion of decibels - there are probably formulas out there to
try and approximate that logarithmic curve and apply it to your audio to get
a more natural response. Its a interesting topic at least ;)

I have tryed the andreas suggestion, but don't work. The jingle volume
continue to be the previous (fadingIn to 90).
But the strange news is another: if I do a test movie inside Flash, the
sound of jingle is loaded and faded (code below), but if I test within HTML
page, no sound is loaded...
How
Well, I have solved both the problems;
1) for the fadeIn / fadeOut question, I assume this solution: instead that
put the loadSound code on main timeline, I have done a new mc, with two
frame inside. At the first frame, insert the code below
stop();
track = new Sound();
