AC3 format: AC3 is a file extension for surround sound audio files used on DVDs format. AC3, the abbreviation of Audio Coding, is the synonym of Dolby Digital audio codec. Dolby Digital (code-named AC3) is a compressed, lossy surround sound format that boomed with the rise in popularity of DVD in the late 1990s and early 2000s. The AC3 file format was created by Dolby Labs for use in a Dolby Digital audio on DVD, Blu-ray and other digital video formats. AC3 stands for Audio Coding 3. Except for Dolby TrueHD, the audio compression is lossy. And Dolby Digital is the common version containing up to six discrete channels of sound. AC3 increases fidelity over its previous surround sound standard, Pro-logic, with independent tracks for each of the 6 speakers, a 16bit sampling at 48khz rate compressed by 10- 12 times, making for a total bit rate of 384kbps. The system is used in bandwidth-limited applications other than DVD-Video, such as digital TV. The AC-3 standard allows a maximum coded bit rate of 640 kbit/s. 35mm film prints use a fixed rate of 320 kbit/s, which is the same as the maximum bit rate for 2-channel MP3. DVD-Video discs are limited to 448 kbit/s, although many players can successfully play higher-rate bitstreams (which are non-compliant with the DVD specification). HD DVD limits AC-3 to 448 kbit/s. ATSC and digital cable standards limit AC-3 to 448 kbit/s. Blu-ray Disc, the PlayStation 3 and the Xbox game console can output an AC-3 signal at a full 640 kbit/s. Some Sony PlayStation 2 console games are able to output AC-3 standard audio as well, primarily during pre-rendered cutscenes. Dolby is part of a group of organizations involved in the development of AAC (Advanced Audio Coding), part of MPEG specifications, and considered the successor to MP3. It is also the standard audio format for HDTV programming. With one digital cable from a DVD player and ultimately other sources like satellite and digital cable boxes, home theater enthusiasts could get discrete surround sound for six or more channels. This means that they could hear unique sounds coming from each of their rear speakers, which created much more detailed, cinema-like surround sound effects at home.
