Sound for film started to become digital during this time period. Straying away from analogue equipment to DAW such as pro tools. It started with Gary Rydstrom creating sound for Luxo Jr. He used synthesisers and pro tools to create a life like sound to the animation. Creating audio for animation at this time was very basic and Gary managed to add human attributes to the character on screen.
He did a similar job on Toy Story 1995. With Woody and Buzz Lightyear having specific choices for their speakers. With Woody being older Gary decided to make his speaker sound like an old record inside him and Buzzs to be a modern speaker system. These key choices made him a great sound designer for picking out tiny differences that govern your thoughts during the movie.
On Jurassic Park 1993 Gary did the same with incredible work creating sounds for the dinosaurs. Layering up 5 animals to create the roar. He noted that Pro Tools helped the sound editors see the waves for the first time, and to hear all the sounds played together simultaneously which wouldn’t be possible in the past before DAW programs.
The Matrix 1999. One of the first movies to have all digital sound effects. This was difficult as the computer systems were still sketchy and prone to crashes and losing things. But on the other side the computer allowed for different techniques that analogue didn’t.
