Yesterday I drove up to Dolby Labs in San Francisco for a demonstration of their 7.1 surround sound on a newly mixed Toy Story 3. 7.1 channel surround sound is nothing new, in fact you might have a home theater that uses it now. What Dolby did was work with Pixar who designed 7.1 sound into the movie instead of adding it as an afterthought. The result was a very impressive, immersive audio experience. The fact that the demo was at Dolby Labs who has an acoustically-perfect theater with state-the-art equipment didn't hurt. By opening day, over 250 theaters nationwide should have upgraded their sound systems to provide the best 7.1 audio environment for this new 3D movie from Walt Disney and Pixar. We also watched some remixed clips of other Pixar movies like Up and The Incredibles which were equally amazing with sound coming at you from all directions. Home theater owners will have to wait for the Blu-ray release of Toy Story 3 but after that more "original-mix" 7.1 movies should start to appear. We recommend you catch Toy Story 3 (in 3D) at a cinema with quality sound.
