This is a simulation of firework.
Why there is a delay of the sound?

Can you estimate how far you are away from the place if the delay time is 0.8 second?

Enjoy it!

More information are required to know what might cause the problem.
Can it view other java program? Can you provide error message from java console?

i suspect your current applet's implementation of the sound
sound1 =flying up
sound2 = explode

does not coincide with real fireworks
for example i check this video
http://youtu.be/xF9I-9bzyhE
<iframe width="425" height="349" src="http://www.youtube.com/embed/xF9I-9bzyhE" frameborder="0" allowfullscreen>
the sound starts from xi after immediate after t2=t-delta

can check? i found a bug i think after i set delta = 0; the flying and the sound1 does not coincident
