Synthesized

A girl is testing her new phone quality with her sister while walking near the edge of a cliff. The former was never heard from again.
Consists of an echoing scream, and white noise.

Magical-sounding synthesized noise with vibrato ascending in pitch. Originally used for a wizard summoning a cage with magic. Created using DrPetter's sfxr.

Simulated gunshots made with Audacity (and popped balloons) for a LibriVox project

I was recording something completely different when the smoke alarm went off. So, makin' lemonade, and uploading it here!

Sound heard before an annoucement, while waiting, on a wharf, for a boat (July 2008).

The file consists of 7 variations of this rustling bulletin boards sound.

I was tapping a pen, increased the bass, lowered the pitch and added echo to it, and it now it sort of reminds me of simulated fireworks.

Someone unlocked his car alarm using a remote key outside my window. It beeps only twice, and I duplicated it 2 times to make it longer.

Toy phone. Baby toy with large buttons to press. Looks like a house. The telephone receiver and dials are build into the roof. :)

This time the battery is so empty, all sounds are gone weird.

squeezing the last sound from the circuits of a hacked, bent and broken toy keyboard.
