This is a charged up explosion i made for my project. It is used when a robotfalls on the ground and slows builds up then explode. I used a laser sound modified it with audacity, and combine with some smaller explosion and edited explosion sound with audacity.
Sound of a bomb falling from the sky. Made using synth. It's free, but please let me know what it's used in, always interested to know!. Www. Daleaudio. Comtwitter - @dalegrins.
It is an explosion of a bomb of normal length, like a grenade i think. However, i created it with this free program to create sound effects http://labbed. Net/software/labchirp/.
A rough analog to an explosion, a work in progress, could be coupled with sounds of trash and debris to make the sound fuller. May fit as an artillery sound effect.
A beeping noise, with long pauses in between beeps at first, then shorter and shorter until a continuous beep. . . Could be used like a timebomb i guess.
