Has anyone got any tips on creating/recording electronic spark/arcing sounds? Is there anyway to create these without an arc welder or a tesla coil?
There was a thread on Twitter about this last year - challenging, eh? While ideas thrown around included miking fluorescents, buzzes, hums, and even the sound of packing tape for short static-y bursts, the best idea I came across was this brilliant guest contribution on Chuck's blog. Bug zappers, who knew?
Fireworks -- Specifically sparklers. Every year, my friends and I get together for the 4th of July, and one of our favorite things to do is to bundle as many of those cheap metal sparklers together as we can (200 is our current record) and light them all off at once The sound is awesome, but don't look directly at it.
