Information about FLAC and AC3 file formats

Full name FLAC - Free Lossless Audio Codec Audio Coding 3
File extension .flac .ac3
MIME type audio/x-flac audio/ac3, audio/vnd.dolby.dd-raw, audio/x-ac3
Developed by Xiph.Org Foundation Dolby Digital
Type of format Audio Music File
Description FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio and is also the name of the reference codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to 50-60% of its original size and decompress to an identical copy of the original audio data. 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.
Technical details The technical strengths of FLAC compared to other lossless formats lie in its ability to be streamed and decoded quickly, independent of compression level. Compared to compressed audio formats, FFmpeg's FLAC implementation was noted to have the fastest and most efficient embedded decoder of any modern lossless audio format. 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.
