What is AC3
AC3 is a kind of file type that is primarily associated with 'AC3 Audio File Format' by Dolby Laboratories.
Dolby Surround Audio Coding-3 (AC3) is a 6-channel, audio file format by Dolby Laboratories that usually accompanies DVD viewing. It operates 5 channels for normal range speakers (20 to 20,000 Hz) and the 6th channel reserved for low-frequency (20 to 120Hz) sub-woofer operation.
Note: Human's audible range of frequency is typically between 20Hz to 20kHz (that's 20,000Hz) and this range is called sonic. Anything below the range is referred to as infrasonic whilst anything above is ultrasonic.
