Sci-fi warning sound effect that was created using the free and open-source software zynaddsubfx, you can use the sound however you like, change the pitch of the sound effect to suite your needs, good for video games.
A sound of a sci-fi sniper rifle and reload. Made in ableton 10 with the help of xfer serum and a bunch of processed and resampled oneshots (which were also made either in serum, or granulator, or some other processing tools).
Synthesized sci-fi shooting. This is a one of the results of my attempt to complete a school assignment. We were supposed to create a gun or canon fire sound with audiogen synthesizer. Let say that this is my best result that could be "loosely" called a gun firealthough it has a sci-fi spin on it :-).
A short intro. Perfect for games and films with retro or classical sci-fi style. Sound is completely free, it was made in lmms using zynaddsubfx (both open source and free).
Recording of pc boot up. Recorder is placed near hdd. For the first portion of sound i recorded electronic cat repelent and glass, and then speed it up. Everything is mixed together and this is the result.
