Sound designer Pierre Mendola created a specialized, modern T-Rex roar for a personal animation project, detailing his layering process of animal sounds, physical elements, and Ableton Live processing in a tutorial. This approach contrasts with the original 1993 Jurassic Park roar, designed by Gary Rydstrom, which featured a mix of tiger, alligator, and baby elephant sounds. Watch the tutorial and hear the sound design on Pierre Mendola's YouTube tutorial . T.REX ROAR - Sound Design - Pierre Mendola
