Fading sound in/out

Question

I have a background sound playing in an endless loop. I want it to fade out when the user does press a button.

I tried the following:

• A DirectSoundOut

Answer 1

Or you can just, do this:

while (waveOut.volume > 0.1)
{
  waveOut.volume -= 0.1;
  System.Threading.Thread.Sleep(10);
}

^ An example of a fade-out. I use it in my own programs, works fine.
