Hello!

I am making a futuristic neon vectrex-like shiny glowy game (see my avatar to understand).

I am wondering what sound to make, to signal explosions... It have to be clear that is a explosion, yet it is NOT supposed to sound like a real-world explosion, because the explosion in the game is just some particles flying around (purple stuff on my avatar), they are not gunpowder burning very fast and causing expanding sound waves...

So, how I make a non-real explosion that is still a explosion?

edit a real explosion sample with a flanger or phaser? use a noise gate destructively? play a synth chord or note, then automate a booster to crescendo into the sound, and compress it last?

just throwing ideas out there.

The best bet is using FM synthesis and automating the amount of FM (frequency modulation) to shape it into an explosion-type sound. This works REALLY well if you use simple analog waveforms and use FM with some white noise or similar. Add some reverb/delay and serve!

A modular or semi-modular synth plug-in would help with this.. I mainly use Reason so I wouldn't know a good free one.. Crystal perhaps?

Yes, personally I think FM synthesis is the way to go for these kinds of effects. I made a pack of FM sound effects not long ago for a competition here: http://mixtape.be/stuff/fmsfx-boomlinde.rar

Now I wonder, automate to where? O.o

I have no idea of what is supposed to sound like a explosion (except it go boom).
