Notes about the AC3 file extension:



Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The AC3 file type is primarily associated with 'AC3 Audio File Format' by Dolby Laboratories.

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.

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.
