Most of you should be already be familiar with that eerie screaming/alarm sound in the Prometheus trailers. I want to make a parody on Prometheus and would prefer it if I used original not-ripped-from-Hollywood sounds. This is more about identifying the elements that make up the screaming/alarm sound than it is a request, but if someone can recreate it, I will eternally grateful.

It sounds human, but somehow not.

I gave it a "quick" and dirty try:

The ingredients are the sampler petri-foo, Audacity, Virtual MIDI Keyboard for pitch wheeling, an effect from the software synthesizer Yoshimi, surprisingly close to the scream as it even starts with a boom (too light by itself), synth strings from Yoshimi to reinforce the scream, and then these:

For the initial boom boost,

For the sort of pneumatic sound pitching down right after the boom,

66364__reinsamba__1243-pressure-cooker.wav

For both the low continuous drone and the mid one that pitches up,

Wow, that's very good. Thanks copyc4t.

You're welcome, it was fun to try
