Hi!
What is the best way to manage sound fx? In my game, you have to shoot asteroids and enemies to get as much points as possible. Everytime I shoot an object, It plays an explosion sound I add to the object I shoot, but when I shoot many objects at the same time, the explosion sound overlap each other. I don’t know how to solve this. I have seen some Sound Managers on the Asset store, but I haven’t tried them, so I don’t know if those will solve the problem.
Btw, I use Playmaker.
I really appreciate if I can get some help with this. 
If two explosions happen almost at the same time I would expect to hear both of them. Why should they not overlap? But maybe you are getting some kind of distortion caused by the overlapping? You can try reduce the volume of each source, or make them shorter in duration. You could also dynamically reduce the volume of each sound in a script depending on how many are playing at the same time. For the type of game you describe, I would tend to make any quick-fire effects quite short in duration.
Hi!
The problem is that explosion sounds are very noise, so it will be too loud for the speaker.
But I tried to stop the explosion sound before it plays again. It works, But I can also try as you say to have a shorter sound and reduce the volume.
this is especially a problem when the sfx are normalized, I also suggest to lower the volume anyway.
