How were the predator linguistics and sound effects for the alien created?
Recording sound for AVP: All Predator and Alien sounds were gathered especially for AVP using the latest digital recording technology. A specially developed tungsten carbide microphone was built for our sound designers that could deal with the high level of noise each of the species made and ensured a high degree of protection from various acidic fluids they excreted. Most of the Alien recordings were made early in the morning in the open usually from one of the various reinforced compounds they were kept in during filming. Essentially Aliens are more dangerous at night, so recording them in the early morning sun allowed a degree of safety for the sound designers as the Aliens were at their least active period. In order to get the full range of vocal noises Aliens produce, the microphone was hidden inside a turkey and swung from a boom arm 20ft above the compound. Turkeys are the Alien equivalent of our bar snacks, and they become very animated and vocal when one was swung out of reach
