Notes about the AC3 file extension:

Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

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.
