Description AC3 is an audio file specifically developed by Dolby Digital to provide surround sound audio. The format is used for audio on many DVDs and Blu-Ray media. For the file to be correctly decoded and output, a DVD player with a Dolby Digital compatible home cinema system is required. It became the de facto standard for surround sound and has held that position since its inception in 1992, with it coming to home cinema in 1995. MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.
Technical details AC3 allows for separate audio to be defined for each of the six speakers in the classic cinema and home cinema setup. This produces the effect of surround sound on the person listening to the audio file. The six channels consist of right front, center, left front, rear right, rear left, and a subwoofer. Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.
