Solving Format Maze Enables Best Audio in Home Theater

摘要

People buy home theater systems so that when they watch movies at home they will get the same visual and audio sensation that they would get in the theater. Normally, when selecting such systems, buyers take the visual experience into consideration first. They want to see clear images on a big screen. However, sound is also important. Home viewers want to experience the same audio sensations that they hear in the theater. That includes, for example, surround sound, which is often essential in setting the right psychological mood corresponding to each scene. For instance, a filmmaker can create an illusion of time stopping by instantly eliminating sound during a normally noisy scene. Low-frequency sound coming from a subwoofer gives a sense of anxiety or fear.
