A long bomb noise. . . Sounds sort of like a nuke i guess, even has debris falling afterwards. Made by popping a little trick noisemaker by the mic and slowing it down.
Sound of a fireworks fuse lighting up and burning. An irregular, low, hissing, noisy sound. Clean close-up 48 khz recording with slightly over emphasized low-end.
Cartoon-style bomb launch and distant explosion. Doppler shifting whistle starts at centre and pans to extreme right with fadeout. A muted detonation follows at extreme right - a non-realistic and short explosion. Created with ni fm8 running as a vsti inside flstudio 11 with a touch of fl reverb2. The "projectile" whistle is a soft square wave lightly modulated by a sinewave at 6x the frequency of the square wave fundamental to give it a touch of metallic ringing.
