About the AC3 format
AC3 (Dolby Digital)
Dolby Digital appeared in cinemas in 1992 and became the standard for DVD sound. It stores up to 5.1 channels with lossy compression at up to 640 kbps.
Separate .ac3 files are usually extracted from films. For a phone or a car they are converted to MP3 - the surround sound is mixed down to stereo, because MP3 holds at most two channels.
Best for surround sound of films on a home theater system.
