🔸 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. Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. ISO and IEC have standardized AAC as part of the MPEG-2 and MPEG-4 specifications.
🔸 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. AAC supports the inclusion of 48 full-bandwidth audio channels in one stream plus 16 low-frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.
