I just had a play.
Starting with an explosing effect I happen to have in my collection, I applied a distortion effect (Effects/Special/Distortion) and got a very similar sound. With a bit of editing to give the stutter effect and tweaking of the distortion, I think a few more minutes would have been virtually identical.
FYI I used the "Maximum Pain" preset in the Distortion menu...but others are worth experimenting with.
If you don't have a handy explosion lying around, join www.freesound.org. They have tons for free--you want a fairly big rumbly one.
Hope this helps,
So you added the maximum pain to the explosion or to the actual clip?
I added the distortion to my clean recording of an explosion. After doing that, by the way, you'll have to crank your levels way down.
Okay...just so you can see if I'm on the right track, here's my original explosion:
Then the whole explosion after distortion is applied and levels adjusted:
And finally some spaces edited in (I didn't bother copying the exact timing in your original but it gives you an idea):
As I say, the above is 5 minutes work. With more time and effort I'm sure something virtually identical is possible.
very helpful, so how would you recommend I go about changing the pitch slightly to get those high and low notes?
Pitch shifter in Audition (probably before the distortion thought it might be worth experimenting both ways) for find different explosions as the original and perhaps mix them together.
