What is a AC3 file?

A file with an AC3 extension uses lossy compression to reduce the overall size of a file. AC3 stands for Audio Codec 3 created by Dolby Laboratories. This type of file supports the surrounding sound. It has a separate track for each of six speakers of a surround sound setup. One speaker is dedicated to low-frequency subwoofer output, while others are dedicated to the normal range. It means that the AC3 format has a 5:1 surround sound setup. This type of file is mostly used for audio in movie theaters, video games, and DVDs.
