Sound Ideas Science Fiction Sound Effects collections allow monsters, ghosts, space ships and dinosaurs to wander through your productions freely. There are ambient tones and backgrounds to establish the perfect other-world atmosphere – there are alien cries and voices to populate your new planets – and there are phasers and stun guns to keep all of the aliens in line. With Science Fiction androids, morphing creatures, twisted and cracking bones for horror and torture scenes, these sound effects colonize and inhabit the worlds you create.
