AC3 VS MP3

MP3 is the most popular and commonly used audio format and most audio files on the Internet are stored in MP3 format.

AC3 (Audio Codec 3) is a synonym of Dolby Digital developed by Dolby Laboratories. It is widely used for DVDs, Blu-ray, digital video streaming, TV broadcast, etc.

AC3 is a surround sound format with multiple audio channels, mainly used in DVDs and Blu-rays, but it has limited device support.
